Conditions at a glance
What stood out in the forecast
Wind
Good10 kt · BF 4
Sustained to 10 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.
Rain
Poor81%
52.9 mm total · 81% peak chance · 6 wet hour(s)
6 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
Good26°C
Air 19–26°C · feels like 19–32°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
Poor0.05 nm
Lowest 0.05 nm · best 9.3 nm today
Sight distance down to about 0.05 nm — treat it like restricted visibility: slower speed, extra lookouts, sound signals where rules require, and AIS/radar if fitted. Ferry lanes and busy harbors deserve extra margin.
Barometric pressure
Good995 hPa
995 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
FairUV 7
High index — plan sun protection before you leave the dock. · peak near 12:00
UV 7.0 is elevated. Cloud cover does not block all UV — protect skin and eyes, especially on white decks and sails.

What should I do?
What to do next
Best window starts around Today 6:00 AM
Conditions should improve around Today 6:00 AM (Central Daylight Time) — consider delaying departure until then.
At harbor: Sat, Jul 4, 6:00 AM (Central Daylight Time)
Pack full wet-weather gear
Rain in the forecast — stow charts and radios in dry bags; visibility drops quickly in squalls.
Reduce speed and watch for traffic
Low visibility makes collisions and navigation errors more likely — use radar and AIS if equipped.
Consider a sheltered route
Stay inside the bay or in the lee of the land if you go out.
