|---|---|---|---|---|---|---|---|
| ECMWF (51 scenarios) | 0% | 63% | 92% | 74% | 55% | 47% | 34% |
| GFS (GEFS, 31 scenarios) | 26% | 68% | 73% | 50% | 13% | 19% | 23% |
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
Thu 29: 8 · Fri 30: 9 · Sat 31: 8
| Index | Level | What to do |
|---|---|---|
| 0–2 | low | No special protection needed. |
| 3–5 | moderate | Hat, sunglasses and sunscreen around midday. |
| 6–7 | high | Sunscreen, hat and shade between 12 and 4 pm. |
| 8–10 | very high | Avoid the midday sun; reflection off the water adds to it. |
| 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.
