Sailing notes
Shallow coral heads on reef approaches; hurricane season demands close weather monitoring June–November.

Easterly trade winds prevail in winter; summer brings lighter variable winds and convective squalls.

Conditions at a glance
What stood out in the forecast
Wind
Good12 kt · BF 4
Sustained to 12 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.
Rain
Poor23%
60.5 mm total · 23% peak chance · 2 wet hour(s)
2 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
Fair30°C
Air 25–30°C · feels like 25–36°C
Feels-like 25–36°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
Poor0.3 nm
Lowest 0.3 nm · best 12 nm today
Sight distance down to about 0.3 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
Good1017 hPa
1017 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 9
Very high index — limit bare-skin time on deck. · peak near 14:00
UV 8.9 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.
