Chance of rain from the ensemble models

ECMWF (51 scenarios)	2%	0%	49%	49%	10%	43%	49%
GFS (GEFS, 31 scenarios)	0%	0%	16%	13%	4%	6%	24%

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.

Outlook

How the coming weeks and months compare with what is normal for the time of year. It is a trend, not a day-by-day forecast.

Next few weeks, compared with normal: a bit warmer, normal rain and a warmer sea.
