SLO County weather forecast for the week of August 1: Warm temperatures and winds
After an extended period of gentle to moderate (8 to 18 mph) northwesterly winds, low swell conditions, seasonal temperatures and mostly overcast skies along the coastline, strong to gale-force (25 to 38 mph) northwesterly winds, an increasing sea and swell, warmer temperatures and clearing skies will develop on Tuesday through the rest of the week.
High pressure retreats eastward this weekend as a trough of low-pressure approaches the Central Coast resulting in a deeper marine layer with areas of fog and mist and cooler temperatures.
Elsewhere, subtropical moisture will continue to stream northward, primarily across the Central Valley and the Sierra Nevada.
The beaches will remain in the 60s under mostly overcast skies, while the coastal valleys (Santa Marina and Lompoc) will range between the high 60s to low-70s on Saturday and Sunday.
The inland valleys (Santa Ynez) are forecast to reach the high-80s this weekend.
Temperatures will begin to trend warmer on Tuesday through Friday as the low-pressure system departs eastward and high pressure builds behind it.
This condition will produce strong to gale-force (25 to 38 mph) northwesterly winds along the coastline, mostly clear skies and warmer temperatures.
Subtle changes are anticipated next weekend, with fair and dry weather except for night and morning coastal low clouds, with seasonable temperatures near the coast and slightly above normal far inland.

This northwesterly sea and swell will further build to 6 to 8 feet (with a 5- to 8-second period) on Thursday through Friday.
