Cowes: a departure-source desk, not a generic city forecast.
Forecast sectors and coverage
Combine the applicable Met Office inshore sector with Cowes Harbour Commission information. Harbour notices and observed weather/tides are local products; check their issue/measurement times independently.
Weather-sensitive legs
Distinguish Medina exit from the Solent and an onward Channel leg. Harbour high water is not a universal slack-current time; use current local tidal-stream and approach information at the actual exit ETA.
Observations, sea state and reassessment
Confirm the exact berth/entrance and an observation representative of the exposed leg, if available. Inspect timestamp, sensor status and forecast issue separately. Missing observations or local approach/current information remain explicit gaps; this page does not certify depth, navigability or port permission.
Worked planning scenario — not a live forecast
Compare two departure times at the harbour exit, first exposed leg and arrival ETA. Record the next official check and a verified alternative before the point of commitment. If the later option is better only at the berth, it has not yet improved the passage as a whole.
Official products by task
- Met Office inshore waters & strong winds — Named coastal sectors and strong-wind warnings; do not substitute a land warning.
- Met Office Shipping Forecast — Larger sea areas, including Channel and North Sea sectors; match against the coastal product.
- Cowes Harbour Commission — Local harbour weather, tides and notices; check the original notice and observation time.
Sector names help you locate the issuing product; they are not an automatic route-coverage match. Open the current issue and check boundaries, issue time and validity. This page does not display current warnings; an unavailable product does not mean no hazard.
Waters and sailing options
- Solent and Isle of Wight
Pair marine wind warnings with local tidal-stream and harbour information.
Countries & territories
- United Kingdom
Combine named inshore sectors, the Shipping Forecast and local tidal/harbour information.
Map orientation
The approximate map centre is not an approach waypoint, track, depth survey or forecast-zone boundary. The third-party map loads only on request.
Build your passage brief
Bring your route, leg timings, vessel and crew profile, checked sources and reassessment triggers into the brief. Personal AI analysis and expert review are available to invited closed-test participants; a port page does not extend the calculation service’s coverage.

Prepare the berth-to-exposure sequence
Start the Cowes brief from the actual berth, not the approximate map centre. List the Medina/harbour exit, intended Solent direction and first exposed sea leg with estimated times. Open the Harbour Commission's current notices separately from its weather/tide information, then pair the Met Office marine issue with the outward and return periods. The result is a source checklist for the real departure, not a generic Cowes city forecast.
- Cowes Harbour Commission — Local harbour notices, weather and tide entry points; not all Solent waters.
- Met Office inshore waters — Named British coastal sectors, marine strong-wind warnings and sea state.
Update what changed, retain what is still valid
Before leaving, record the latest notice, wind observation time, marine issue and applicable local stream publication as separate items. If a delay shifts the exit or return, rerun the timing comparison and check whether all items still apply. A harbour high-water time is not a universal Solent slack. If the exposed-leg observation or approach evidence is missing, name that gap rather than showing an apparently complete green departure summary.
