What stood out in the forecast
Wind
Good12 kt · BF 4
Sustained to 12 kt · gusts to 18 kt · BF 5
Beaufort 5 — a workable breeze for most day sails. Watch for funneling between headlands and tall buildings near harbors; local gusts can exceed the open-water forecast.
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
Fair36%
0.4 mm total · 36% peak chance · 19 wet hour(s)
Showers possible across 19 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
Good18°C
Air 15–18°C · feels like 11–18°C
Comfortable air temperatures for deck work, but water temperature may still be much colder — a dip without proper gear can shock even on a warm day.
Visibility
Good4.9 nm
Lowest 4.9 nm · best 5.4 nm today
Generally clear sightlines (about 9.0–5.4 nm). Good for spotting traffic and shoreline references — still verify charted marks; glare and spray can fool you even on “clear” days.
Barometric pressure
Good1021 hPa
1021 hPa ↑ rising (4 hPa change)
Pressure has risen about 4 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 4.9
Moderate index — standard protection recommended. · peak near 12:00
Lower UV today, but reflection off water still adds exposure. Sunglasses and SPF remain cheap insurance on the water.
