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.

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).

3–5	moderate	Hat, sunglasses and sunscreen around midday.
6–7	high	Sunscreen, hat and shade between 12 and 4 pm.

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.
