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: 5 · Sat 31: 3 · Sun 1: 4
| 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.
Barometric pressure
- ↗ Rising Anglers say fish bite less for a while
- → Steady · now Anglers expect normal activity
- ↘ Falling Anglers say fish feed more before the change
Steady now (+0.02 inHg in 3 hours). It barely changes over the next 48 hours. Steady pressure: anglers expect normal activity. Fast changes, either way, tend to affect fishing.
Air and pollen
Saharan dust: light.
Pollen: Copernicus CAMS model (a rough guide, not a pollen trap). Levels use each type's usual thresholds.
