This is a pre-passage source and decision desk, not a current forecast or clearance to depart. The map is centred approximately on the area, not on your route or a forecast-zone boundary.
Sea-area bulletins and archipelago or fjord conditions have different scales. In season, check ice and sea-level products; in narrow passages also examine current and visibility, not only mean wind.
1. Primary sources
Open current bulletins and warnings for every sea area on the route. These links are starting points, not a promise that each covers the whole location; if unsure, identify the issuer through WMO–IMO.
2. Route and local effects
High-latitude voyages need current marine, ice and communication planning.
Barents Sea and Svalbard passages are high-latitude operations with ice, darkness and sparse communications in addition to weather.
Combine MET Norway marine warnings with the Norwegian Ice Service and current local restrictions. An ice chart has issue time and uncertainty; it is not a navigable-route clearance.
How to use this source set
Start with the warning, then the marine text for the exact named area. If the route crosses a zone boundary, obtain both bulletins. Note issue and valid times, wind units and the meaning of wave height. Where a link opens an agency portal, navigate to its current marine product; a homepage is not itself a forecast.
Compare with an exposed station or buoy if available. Check its position and observation time: a sheltered station does not overturn a warning for an open channel. If a bulletin is missing or stale, identify the issuing service via WMO–IMO and defer the decision until current information is available.
Before-passage check
- Mark departure, exposed legs, arrival and feasible diversions; find the responsible named marine areas for each.
- Check warnings, issue and valid times; assess conditions when you expect to reach each leg, not only at departure.
- Compare wind and gusts, waves and swell, visibility, thunderstorms and local effects; do not infer a strait from a sheltered harbour.
- Compare recent observations where available, noting their time and exposure; a mismatch calls for another check.
- Set the next bulletin check, a reassessment trigger, an alternative and a backup communication channel.
Model map — optional
Windy is a third-party model display, not the issuer of official warnings. Choose a layer and check its valid hour and model run. Nothing loads until you click.
Without JavaScript, open the map separately.
If connectivity fails
Before departure, save the current official text bulletin and warning with issue time. Arrange another way to receive updates, such as an appropriate coastal broadcast, NAVTEX or satellite channel. A saved map cannot replace new warnings.
How to choose weather tools · All sailing areas
Scope: Source list assembled 25 September 2026; check its freshness and coverage before use. This public area guide is not a current personalised forecast, navigational notice service or safety verdict. Personalised forecasts with AI and experts are in closed testing; public booking is not open. The skipper makes the decision.
Ice-information freshness is part of the weather briefing
For a Barents–Svalbard planning scenario, retain marine warning, wave forecast and ice product as distinct records. MET Norway links the Norwegian Ice Service; inspect issue time and coverage before using a chart. The ice edge can move after analysis, and a regional chart cannot certify a clear lead or absence of individual hazards along a yacht track. A summer reputation is not today's ice evidence.

Cold-water exposure changes the passage margin
Evaluate weather exposure together with vessel capability, crew protection, daylight and communication endurance. The same wind or wave number is not an equivalent operational demand for a lightly equipped yacht and a specialist polar vessel. Avoid deriving a universal ice or icing threshold from a model alone. The brief should list missing specialist inputs rather than make an apparently complete route score out of wind and waves.

Expedition alternatives require independent verification
If ice information ages, communication fails or progress drops, reassess the onward weather horizon and practical refuge options before the next commitment. A coastline visible on a map is not a verified port, landing permission or reachable rescue service. Confirm current local restrictions and specialist support independently. This area desk is a source-and-decision aid; it cannot replace expedition planning or a qualified polar navigator's route assessment.
