Conditions at a glance
What stood out in the forecast
Wind
Good11 kt · BF 4
Sustained to 11 kt · gusts to 17 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
Poor85%
41.0 mm total · 85% peak chance · 14 wet hour(s)
14 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
Fair29°C
Air 24–29°C · feels like 24–32°C
Feels-like 24–32°C once wind and humidity count. Layer so you can cool off in sun and warm up when wet; shivering crews make poor decisions.
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
Good1007 hPa
1007 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
PoorUV 8.4
Very high index — limit bare-skin time on deck. · peak near 11:00
UV 8.4 is very high — water reflection adds exposure you do not feel on land. Broad-spectrum SPF, hat, lip protection, and hydration reduce fatigue; consider shade breaks if you are out all day.
