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.
Onshore or offshore wind?
Today, from the southwest: cross-offshore. Calmer water near the shore, and bait and boats drift out to sea.
On Friday 30, from the west: offshore.
The coast here faces southeast. We work it out from the OpenStreetMap coastline.
