Each model's day runs midnight to midnight local time; models that reach fewer days are left blank. Rain: daily total. Wind: the day's highest average wind and, in small type, the strongest gust. Highlighted: values that stand out from the rest. The chance of rain comes from many runs of the same model with slightly different starting data.

UV index
Fri 30: 9 · Sat 31: 4 · Sun 1: 4
| Index | Level | What to do |
|---|---|---|

| 11+ | extreme | Avoid the sun between 11 am and 5 pm; protect yourself even if it is cloudy. |
Reflection off water and sand adds radiation: protect yourself more on a boat or at the beach.
