What stood out in the forecast
Wind
Fair17 kt · BF 5
Sustained to 17 kt · gusts to 19 kt · BF 5
Beaufort 5 — manageable for experienced crews but not relaxing. Reef before open water, plan a route with lee shore options, and expect harder docking and mooring picks.
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
Fair46%
0.6 mm total · 46% peak chance · 14 wet hour(s)
Showers possible across 14 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
Fair29°C
Air 28–29°C · feels like 28–34°C
Feels-like 28–34°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
Fair1.1 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
Good1014 hPa
1014 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 9.5
Very high index — limit bare-skin time on deck. · peak near 13:00
UV 9.5 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.
