What stood out in the forecast
Wind
Good11 kt · BF 4
Sustained to 11 kt · gusts to 15 kt · BF 4
Beaufort 4 — 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
Fair20%
0.3 mm total · 20% peak chance · 2 wet hour(s)
Showers possible across 2 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
Poor33°C
Air 28–33°C · feels like 28–39°C
Feels-like 28–39°C with spray — dress for immersion, not the marina thermometer. Cold shock and hypothermia are real risks if someone goes overboard; carry spare layers in a dry bag.
Visibility
Good2.7 nm
Lowest 2.7 nm · best 5.4 nm today
Generally clear sightlines (about 5.0–5.4 nm). Good for spotting traffic and shoreline references — still verify charted marks; glare and spray can fool you even on “clear” days.
Barometric pressure
Good1010 hPa
1010 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 8.2
Very high index — limit bare-skin time on deck. · peak near 13:00
UV 8.2 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.
