About sailing in Miami Biscayne Bay

What stood out in the forecast
Wind
Good10 kt · BF 4
Sustained to 10 kt · gusts to 19 kt · BF 5
Beaufort 5 — 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
Fair17%
0.1 mm total · 17% peak chance · 5 wet hour(s)
Showers possible across 5 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
Fair30°C
Air 28–30°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
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
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 9.3
Very high index — limit bare-skin time on deck. · peak near 13:00
UV 9.3 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.
