Conditions at a glance
What stood out in the forecast
Wind
Fair12 kt · BF 4
Sustained to 12 kt · gusts to 20 kt · BF 5
Beaufort 5 — 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
Fair57%
2.1 mm total · 57% peak chance · 13 wet hour(s)
Showers possible across 13 hour(s). Light rain is manageable with good gear; heavy bursts can obscure marks and other traffic — keep a hand on the plotter or chart.
Air temperature
Poor33°C
Air 16–33°C · feels like 13–35°C
Feels-like 13–35°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
Good1018 hPa
1018 hPa ↑ rising (9 hPa change)
Pressure has risen about 9 hPa — weather often stabilizes, though wind and waves can lag by several hours. A positive sign if other factors already look favorable.
UV / sun
GoodUV 5.5
Moderate index — standard protection recommended. · peak near 13:00
Lower UV today, but reflection off water still adds exposure. Sunglasses and SPF remain cheap insurance on the water.
