Conditions at a glance
What stood out in the forecast
Wind
Good8 kt · BF 3
Sustained to 8 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.
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
Good18°C
Air 10–18°C · feels like 7–18°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
Good27 nm
Lowest 27 nm · best 31 nm today
Generally clear sightlines (about 50.2–31 nm). Good for spotting traffic and shoreline references — still verify charted marks; glare and spray can fool you even on “clear” days.
Barometric pressure
Fair1025 hPa
1025 hPa ↓ falling (4 hPa change)
Pressure has dropped about 4 hPa — a common sign of an approaching front or low. Wind often strengthens and seas build over the next hours, sometimes before the sky looks dramatic. SailCall does not measure tidal or ocean currents; check tide tables for harbor streams. Wind against the tide can sharpen chop in narrow channels.
UV / sun
GoodUV 3.5
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.
