What stood out in the forecast

Wind

Good

11 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

Good

0.0 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

Fair

17%

0.1 mm total · 17% peak chance · 1 wet hour(s)

Showers possible across 1 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

Fair

30°C

Air 29–30°C · feels like 29–35°C

Feels-like 29–35°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

Good

5.4 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

Good

1018 hPa

1018 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

Poor

UV 10.9

Very high index — limit bare-skin time on deck. · peak near 13:00

UV 10.9 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.
