What stood out in the forecast
Wind
Fair24 kt · BF 6
Sustained to 24 kt · gusts to 26 kt · BF 6
Beaufort 6 — manageable for experienced crews but not relaxing. Reef before open water, plan a route with lee shore options, and expect harder docking and mooring picks.
Seas
Good0.0 m
Significant wave height 0.0 m
Relatively modest seas today (swell ~0.0 m). Still evaluate harbor entrance and wind against any tidal stream using local pilot notes.
Rain
Poor82%
39.7 mm total · 82% peak chance · 8 wet hour(s)
8 hour(s) with meaningful rain risk — expect reduced visibility, saturated decks, and slower reaction times. Full waterproof layers and clear eyewear help; consider delaying if comfort and sightlines matter for your route.
Air temperature
Poor32°C
Air 10–32°C · feels like 6–38°C
Feels-like 6–38°C with spray — dress for immersion, not the marina thermometer. Cold shock and hypothermia are real risks if someone goes overboard; carry spare layers in a dry bag.
Visibility
Good5.4 nm
Lowest 5.4 nm · best 5.4 nm today
Generally clear sightlines (about 10.0–5.4 nm). Good for spotting traffic and shoreline references — still verify charted marks; glare and spray can fool you even on “clear” days.
Barometric pressure
Good1024 hPa
1024 hPa → steady
Pressure is steady — no strong synoptic system pushing through on this snapshot. Local wind, sea breeze, and geography still dominate near shore.
UV / sun
FairUV 7.5
High index — plan sun protection before you leave the dock. · peak near 12:00
UV 7.5 is elevated. Cloud cover does not block all UV — protect skin and eyes, especially on white decks and sails.
