What stood out in the forecast
Wind
Good9 kt · BF 3
Sustained to 9 kt · gusts to 13 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
Fair12%
0.0 mm total · 12% 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
Good25°C
Air 19–25°C · feels like 19–25°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
Good5.4 nm
Lowest 5.4 nm · best 5.4 nm today
Generally clear sightlines (about 10.0–5.4 nm). Good for spotting traffic and shoreline references — still verify charted marks; glare and spray can fool you even on “clear” days.
Barometric pressure
Good1016 hPa
1016 hPa → steady (2 hPa change)
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 6.9
High index — plan sun protection before you leave the dock. · peak near 12:00
UV 6.9 is elevated. Cloud cover does not block all UV — protect skin and eyes, especially on white decks and sails.
