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.

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).

Humidity and dew point

Humidity93%

Dew point81 °F

Humidity is 93% now and the dew point is 81 °F. With a dew point this high, it feels muggy. The temperature is very close to the dew point: fog may form.

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

Visibility and fog

Clouds14%

Visibility is good now (15 mi). No fog expected today.

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