Conditions at a glance

What stood out in the forecast

Wind

Good

5 kt · BF 2

Sustained to 5 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

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

Poor

70%

1.4 mm total · 70% peak chance · 11 wet hour(s)

11 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

Good

27°C

Air 23–27°C · feels like 23–29°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

Fair

1.1 nm

Lowest 1.1 nm · best 5.4 nm today

Visibility may dip to 1.1 nm even if the best part of the day reaches 5.4 nm. Haze, rain, or low cloud can hide buoys until you are close — brief the crew on what to watch for.

Barometric pressure

Good

1020 hPa

1020 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

Good

UV 1.6

Low index — still use basics on bright water. · peak near 12:00

Lower UV today, but reflection off water still adds exposure. Sunglasses and SPF remain cheap insurance on the water.
