Each hour comes from the best model for this spot: ICON-EU until Monday 2 8:00 pm; then ECMWF until Thursday 12 4:00 pm; then GFS.

Each day comes from the best model covering this spot: regional ones first (HRRR and NBM in the U.S., AROME, ICON-EU), then ECMWF; day 16, NOAA GFS. Waves: Météo-France up to day 10, then ECMWF WAM, coarser and further offshore. High tides: our own tide calculation.

Chance of rain from the ensemble models

ECMWF (51 scenarios)	0%	20%	12%	43%	10%	11%	18%
GFS (GEFS, 31 scenarios)	0%	13%	15%	36%	11%	17%	19%

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.

The next few weeks look normal for the time of year.

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).

Dew point46 °F

Humidity is 72% now and the dew point is 46 °F.

The dew point is the temperature at which the air becomes saturated: the higher it is, the heavier the air feels.

Visibility and fog

Now23 migood

Clouds20%

Visibility is good now (23 mi). No fog expected today.

The model gives visibility up to about 15 mi: beyond that, the horizon is clear.

Reflection off water and sand adds radiation: protect yourself more on a boat or at the beach.
