Conditions at a glance
What stood out in the forecast
Wind
Good10 kt · BF 4
Sustained to 10 kt · gusts to 19 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.
Rain
Good0%
0.0 mm total · 0% peak chance · 0 wet hour(s)
Little rain expected — one less factor stealing visibility and grip on deck. Still pack a light jacket; conditions change faster on the water than ashore.
Air temperature
Good21°C
Air 15–21°C · feels like 14–21°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
Good5.1 nm
Lowest 5.1 nm · best 18 nm today
Generally clear sightlines (about 9.4–18 nm). Good for spotting traffic and shoreline references — still verify charted marks; glare and spray can fool you even on “clear” days.
Barometric pressure
Good1025 hPa
1025 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
GoodUV 6
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.
