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
Conditions inside a fjord can differ materially from the exposed coastal leg.
A Norwegian coastal leg can leave an exposed sea lane and enter a fjord with sharply different wind and visibility.
Use MET Norway marine products for the exposed coast and local observations for the fjord entrance; do not infer offshore wave height from an inner-fjord station.
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.

Personalised forecasts with AI and experts are in closed testing; public booking is not open. The skipper makes the decision.
A fjord wind reading is local evidence
For a coastal passage through a fjord entrance, separate the outer sea, mouth and inner anchorage. Terrain can make a station's exposure different from the route, so do not use a sheltered inner reading to reject an exposed-coast warning. MET Norway links sea-area and fairway-wave services; use the appropriate product for the exposed leg, and inspect the actual forecast coverage rather than treating every fjord as a modelled harbour.

Swell outside, gusts inside, stream in between
Maintain separate wave-direction/period information for the outer approach and local gust evidence for the inner route. Narrow tidal passages require their own current publication; a water-level forecast is not the flow through a constriction. If the source is a fairway or regional model, keep its scale explicit and do not fill unresolved harbour geometry with confident AI language. The useful brief explains which part is observed and which is inferred.

Shelter must still work after the weather changes
For an outer-coast-to-fjord scenario, test a slower arrival and the forecast direction change at the mouth. Reassess before leaving the last useful coastal shelter if visibility, gust trend or the arrival wave direction no longer fits the plan. An inside route may reduce sea exposure but add narrow-channel workload. Keep communication availability and a current warning update in the plan, particularly when terrain limits reception.
