Meteo — weather, tides, and alerts

The Meteo tab brings together everything you need to read the sea before

you trust it.

Meteo Marine Weather — current-conditions strip, NOAA / Open-Meteo / LIVE / MLLW source badges, the 12h–7d range picker, and the hourly forecast table

A segmented bar at the top has three sections, plus Radar when the

weather map service is available:

Marine Weather — Events — Meteogram — [Radar](#live-map).

Weather pins

Above the segmented bar sits a strip of circular weather avatars — one

for every location you have pinned for weather. Each avatar shows the sky

glyph from that location's saved report plus how long ago the report was

fetched. The ring colour is the age at a glance: white ring while the report

is fresh (under ~3 h), amber as it ages, grey once it is stale (older than

12 h).

  • "My Position" appears by itself. The very first weather the app
  • fetches for your vessel is saved as a report automatically — a My

    Position avatar leads the strip from your first launch, no tap needed,

    and it keeps following your vessel's weather fetches as you sail. Delete

    it and it stays gone until you re-add it with +.

  • Tap an avatar to select it — no pop-up: the dashboard below switches
  • in place, and all three segments now read from that pin's saved report.

    Marine Weather shows the full dashboard for the pin — conditions

    header, range picker, the Sea State simulation, hourly strip, wind,

    precipitation, sea state, visibility / pressure, alerts, the meteogram

    link and the refresh / logbook / remove actions (only the tide curve

    stays with your vessel's station); Events its weather alerts;

    Meteogram the full forecast chart for the pin's coordinate — not

    your vessel's.

    Everything is stored on the device, so it appears instantly and works

    offline; the age keeps counting up so you always know how old what you're

    reading is. Tap the My Position avatar to return to the classic

    current-location dashboard.

  • The selected avatar glows green, with a shimmer that orbits faster
  • the windier it is there — a calm anchorage idles, a gale spins. Its

    small green scope badge jumps straight to the AnchorQueen chart,

    centred on the pin.

  • Every avatar says where it stands. A small badge in the avatar's
  • top-right corner tells you what kind of place the pin is: a brown

    mountain for a point ashore (a marina, a town, a hilltop), a teal

    beach umbrella for coastal waters (afloat, with land within about

    2 NM — where sea breeze and land-limited fetch shape the forecast), and a

    blue waves badge for open sea (no land within reach — the

    synoptic wind, unshielded). The answer comes from the app's bundled

    coastline, so it works offline and appears a moment after the pin.

  • The + avatar appears only while the My Position entry is absent and
  • brings it back.

  • New pins start filled, not blank. A pin dropped near your vessel
  • reuses the weather the app already fetched — the report shows instantly,

    correctly aged to when it was actually downloaded, and only re-fetches

    when it is genuinely stale.

  • Every report names its place. The report header shows a
  • human-readable location under the raw coordinates — *"Kassiopi, Ionian

    Islands · Greece" on land, the sea area ("Aegean Sea"*) offshore — the

    same label the chart's location badge uses, so a pin dropped mid-passage

    still tells you where the forecast applies.

  • The report sheet is the dashboard. Opened from a chart badge or a
  • POI's Weather button, the pin's report is the same Marine Weather card

    stack as above — Sea State included — at full height, in the Meteo tab's

    dark appearance.

  • Refresh Report inside the sheet re-fetches on demand; the app also
  • quietly re-fetches any report older than an hour when it launches.

  • Add to Logbook files the report in your logbook; Show on Chart
  • flies the chart to the pin.

  • Remove Weather Pin asks first, then deletes the location and its saved
  • report.

    Weather pins also appear as round badges on every chart — AnchorQueen and

    the SafeAnchor anchor-watch chart alike — with a compact

    temperature · wind · age caption, and they grey out as their report ages.

    You can hold up to 12 pins; pinning a harbour, marina, or anchorage from

    its detail sheet lands here too (see

    the chart page).

    Marine Weather

    A live dashboard for the nearest station, or any station you save as a

    favorite. At the top of the dashboard is a range picker

    (12h · 24h · 3d · 7d); whatever you pick drives every chart and the

    hourly carousel at once. This range picker has no Pro gate: once you are

    signed in, every plan gets all four ranges; without a captain account it stays

    on 12h. (The [Meteogram](#meteogram-tiers) has its own filter, where

    3d and 7d are Pro or Oceanic Tides.)

    Under the hourly forecast the dashboard shows the Oceanic Tides card — the

    weather pass that unlocks the Meteo tab and the anchor forecasts at full depth

    (radar, 3- and 7-day meteogram, 3-day drift forecast) without a full plan.

    Route weather and pinpoint mark weather stay with Pro and Max. See Oceanic Tides. It is hidden for Max

    captains, who already have all of it.

    Station card

    The card headline shows your location (place and country). The source

    weather/tide station is named just beneath it — that station is often

    offshore or some distance away, so the headline tells you where the reading

    actually applies, while the sub-line tells you which station it came from.

  • Current conditions strip — a row of tiles across the top of the card:
  • AIR, FEELS, SEA, and HUMIDITY, beside the current sky

    icon and description.

  • Source badges — a row of pills showing where the numbers come from:
  • the tides provider (NOAA or Stormglass), the weather provider

    (Open-Meteo or Stormglass), a LIVE / CACHED badge, a PREDICTED

    badge when the reading is filled in from forecast, and the vertical

    datum (e.g. MLLW) when known.

  • Stat strip — when the station was last Updated, the Distance
  • to it in nautical miles, and the Lat / Lon the reading is for.

  • Overflow menu (the … button) — Refresh Forecast, Change
  • Station, Save Station, and Show Map / Hide Map.

  • Station map — collapsible (open it from the overflow menu). Pan it and
  • a centre crosshair shows the coordinate under the cross; tap Fetch

    Data for This Location to pull the forecast for that exact point, not

    just the fixed station pin. Your own vessel and the station are both

    marked.

    Charts and carousel

    All of these follow the range picker.

  • Hourly carousel — a scrollable hour-by-hour timeline; its length
  • follows the range you picked (12 h up to 7 days).

  • Wind & Gust — an interactive trend chart with sustained-wind and gust
  • traces, Beaufort colouring, Strong-breeze (F6) and Gale (F8) reference

    lines, a peak-gust marker, and wind-direction arrows along the top.

  • Precipitation — hourly chance of precipitation, each hour classified
  • as rain / drizzle / snow / fog / thunderstorm, with a 50% "likely" line.

  • Sea State & 3D Ocean — waves, swell, and ocean current in one interactive card. Each row
  • shows the value plus a small "sets toward" compass arrow. Below the telemetry, a procedural 3D ocean view renders physically simulated waves, swell crests, and solar/star illumination driven by real atmospheric data.

  • Pressure & Visibility — an interactive barometric chart with the
  • 1013 hPa standard line, a 1000 hPa "unsettled" line and shaded band,

    ridge/low turn markers, and a 3-hour tendency badge — plus the current

    visibility reading.

  • Tides — an interactive tide curve reconstructed from the
  • high/low waters, with labelled H/L markers, day/night shading, and a

    live "Now" dot. A summary above it shows the next High, the live

    Now height (with a Rising / Falling trend), and the next Low.

    Every chart has a drag scrubber: drag across it and the readout above

    the chart follows your finger; lift off to snap back to "Now".

    3D Sea State card

    The Sea State card visualizes the forecast ocean surface directly on your device:

  • Poster-first & battery-conscious. The card opens showing a static high-fidelity poster frame. Tap the card to wake the live WebGL simulation; tap again to pause. Rendering automatically halts when backgrounded or when device thermals rise.
  • Real and Random. Real (the default) shows the forecast sea for the hour on the scrubber. Random jumps to another look over your own position — Beaufort force 3, 5, 7, 9 or 11, or Sunny, Rain, Thunder, Moon, Fog or Tornado; tap it again for another, or Real to go back. Weather looks keep your time of day, so rain after dark is a rainy night; Sunny and Moon settle on local midday and local midnight, because neither makes sense at the opposite hour.
  • Hour scrubber. Drag the forecast hour timeline to see how wave heights, swell direction, and solar lighting evolve throughout the day and into the night. Light follows the real sun and moon for the pin's position: it comes up with civil twilight, and after dark the card is graded to the light that is really out there — a dark sea with the moon's glitter path and breaking foam as the brightest things in frame, and a horizon that fades into the sky. A moonlit night is brighter than an overcast one; a clear night with no moon is very dark, because at sea it is. The Now hour tracks the clock to the minute.
  • Camera perspectives. Tap the camera button to cycle between Orbit (panoramic sweep at deck level), Deck (low-angle waterline perspective cutting through the swell), and Still (fixed observation angle).
  • Illustrative safety notice. The 3D view is an algorithmic simulation meant for situational intuition. Always consult official meteorological warnings and raw telemetry before making navigational choices.
  • Times and time zone

    Every clock label in the Meteo tab — the hourly carousel, chart hours, day

    separators, tide markers and the day/night weather icons — is shown in

    your device's time zone, the same clock as the rest of the app. This

    holds for saved weather pins and the live-map forecast panel too, so a pin

    in another country reads in your time, not the pin's local time.

    Before 2.4.2 these labels were drawn in UTC.

  • --
  • Where the readings come from

    The Meteo tab pulls live marine data through AnchorQueen's backend, which

    fetches per request and caches the result (the CACHED badge tells you

    when you're seeing a cached pull). The providers:

  • Tides — NOAA tide predictions (relative to the MLLW datum) in
  • NOAA's coverage zones; Stormglass elsewhere, and as a fallback when

    NOAA can't be reached.

  • Weather & waves — Open-Meteo for current conditions, wind, gusts,
  • pressure, precipitation, waves, swell, and current; Stormglass as the

    fallback.

  • History — the Open-Meteo archive, used to fill the comfort and
  • forecast history shown in the Comfort detail sheet.

    The tide curve you see is reconstructed from the high/low waters the

    provider returns — AnchorQueen fills in the smooth shape between each high

    and low (the analogue of the mariner's "rule of twelfths"), so you get a

    continuous, scrubbable curve rather than just a list of times.

    Events

    At the top of the Events screen is a Comfort Meter — a ring showing a

    one-glance comfort score for your current conditions, with the leading

    factor named beside it (e.g. "Moderate Sea State", "+ 2 other factors").

    Use it as the quick "is tonight workable" answer.

    Tap the meter (or the chart button next to it) to open the Comfort

    detail sheet, which plots your recent comfort history and the

    forecast ahead so you can see whether conditions are improving or

    deteriorating.

    Below the meter is the list of active weather alerts for your area —

    gale warnings, storm watches, small-craft advisories. Each alert shows its

    severity and message, and is color-coded by severity (severe / moderate /

    advisory). When nothing is active you'll see a "No active events" state

    instead.

    Radar

    The Radar segment opens an animated weather map on the radar layer,

    already moving: the forecast plays from two hours ago through the next hours

    and loops, so you can watch rain and storm cells travel. After three loops it

    rests on now to save battery — tap or pan the map, or tap ▶, to play it

    again. Tap ▶ / ❚❚ to stop it or scrub the timeline yourself. Radar is part of Pro and of the

    Oceanic Tides weather pass; its upgrade sheet sells

    Pro, and the pass is sold from the Marine Weather dashboard and the Store.

    What you see:

  • Legend card (top left) — the layer's colour scale. Rain and radar are
  • labelled in words (Very light → Light → Moderate → Heavy → Severe →

    Hail); wind, temperature and pressure in your units from Settings → General →

    Units. Forecast · model is a reminder that this radar is a forecast

    from a weather model, not live radar scans. Tap the card to fold it.

  • Your position — a bubble above the blue dot reads the layer at your
  • position for the time on the slider: wind as direction and speed

    (↓ 012° · 12 kn), rain and radar as a word with its intensity (a ⚡ marks

    thunderstorm-strength cells). Where the map shows only a faint cyan haze it

    says Very light; it says Clear only where nothing is painted.

  • Weather pins — every saved pin shows the same value over its name. A
  • grey dot means nothing is falling there; a cyan dot is a very light echo.

    Tap a pin to slide up its hourly forecast panel, synced to the map's clock;

    pull it down to dismiss.

  • Layers (top right) — Radar, Precipitation, Wind, Temperature,
  • Pressure, plus the Wind arrows and Isobars overlays. The arrow

    button next to it centres the map on your position; − / + zoom.

  • Player card (bottom) — the layer, the forecast time, and the
  • forecast range: 12h with Pro, 3d with Max. A Now marker

    sits on the timeline.

  • The dot before the layer name, and on the Radar segment itself, is
  • the data link: green connected (breathing while the map is open),

    amber connecting, red offline. With the segment closed it stays

    steady green while your device is online and turns grey offline.

    On the Free plan the segment shows the same layout over a blurred map,

    without values, and a See plans button that opens the Store's plans. A

    locked 3d button does the same for Pro captains.

  • The Radar segment defaults to the high-contrast black Dark base map for
  • optimal radar visibility. To change it, tap the Layers button (top right of

    the map) — the Map group at the top of the menu switches between Dark,

    Ocean and Satellite. The map reloads in the new style and remembers

    your choice. Satellite is hybrid imagery: it needs Pro, Max or any chart

    region you hold (bought, included, or any region while your 14-day

    full-access window runs); otherwise the pick opens the Store's Charts page

    and the map keeps its current base.

  • Tapping a rainy spot on the Precipitation layer offers View
  • details, which saves a weather pin there and opens its report.

  • Radar needs an internet connection; everything else in Meteo keeps working
  • offline from the last saved reports.

    Meteogram

    A separate, GFS-style graphical forecast in stacked panels, one variable

    per row:

  • Wind direction
  • Wind speed and gusts
  • Temperature (air + feels-like)
  • Pressure (sea level)
  • Relative humidity
  • Precipitation
  • A current-conditions summary card sits on top, and — when the station has

    marine data — a horizontal Marine Conditions strip below the panels

    shows hourly wave height, direction, and period. Time runs along the

    bottom; turn on the value inspector (crosshair) from the … menu, then

    tap or drag to read exact values at any time. The same menu lets you save or

    share the meteogram as a PDF or image.

    Time-range filter & plan tiers

    Above the panels is a time-range filter — 6h · 12h · 24h · 3d · 7d.

    Unlike the Marine Weather range picker, this filter is Pro-gated above

    the free tiers:

  • Free captains get the short-term outlook — 6h, 12h, and up to
  • 24 hours.

  • Pro — or the Oceanic Tides weather pass —
  • unlocks the 3-day and 7-day planning windows.

    On a Free plan the 3d and 7d buttons show a lock; tapping either opens

    the Store so you can upgrade.

    Where the data comes from

    The providers behind Marine Weather, Events, and the Meteogram are listed

    above under [Where the readings come from](#oceanographic-engine); the full

    partner list is in

    Settings → Data Sources & Partners.

    Reading the weather for a decision

    Weather is the single biggest safety factor at sea. A few ways to use these

    screens to make a go / no-go call:

  • Pick a wind window. On the Wind & Gust chart (or the meteogram's
  • wind panel), look for a stretch where both the wind line and the gust

    trace sit below your comfort limit. The Strong-breeze (F6) and Gale (F8)

    reference lines tell you at a glance when it's getting serious.

  • Watch the pressure. On the Pressure & Visibility chart, a falling
  • tendency badge ("Falling quickly", "Falling very rapidly") and the

    shaded sub-1000 hPa band flag an approaching front or squall.

  • Compute your clearance. Drag the tide curve to the time you'll
  • pass, read the height, and add it to the charted sounding depth. If the

    chart shows 1.8 m and the tide reads +0.6 m, you have 2.4 m of water —

    subtract your draft for the margin. Heights are relative to the station's

    datum (e.g. MLLW), shown on the station card.

  • Time shallow passages for slack water — the brief lull around high or
  • low tide — to avoid the strongest current. The Sea State card's current

    "sets-toward" arrow shows which way it's running.

  • Use Events as a gate. A gale or storm alert means stay in port; a
  • Moderate or Rough comfort score means conditions that will challenge a

    novice crew.

  • Pairing with Merconi. When scouting a dive site in
  • Merconi, look for low wave height and an offshore wind

    (blowing land-to-sea) for the flattest, clearest water.

    If something goes wrong

  • The station card is blank — no station could be reached for your area.
  • Open the … menu and Change Station to pick a saved one, or open the

    station map and Fetch Data for This Location somewhere nearer the

    coast.

  • A chart says "not available" — that variable wasn't in the provider's
  • response for this station; try Refresh Forecast from the … menu.

  • The badge reads CACHED — Meteo needs a connection to refresh; the
  • last values are shown until you reconnect. See

    Troubleshooting: offline behavior.

  • Forecast hours look shifted by a few hours — on 2.4.1 and earlier every
  • Meteo time was drawn in UTC. Update to 2.4.2; see

    [Times and time zone](#times).
