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 and normal rain.

Weeks: ECMWF 46-day (average of its scenarios), against the normal of the last 20 years for those dates. Months: ECMWF SEAS5. Rain: total against normal. The further ahead, the closer it gets to normal and the less detail it can give. The long-range sea temperature isn't usable at this spot (the model's grid cell falls on land).
