SLO County weather forecast for the week of June 28: Drizzly mornings, warming by July 4 weekend
The pattern of night and morning marine low clouds with areas of fog and drizzle in the coastal regions that started last week will continue through most of this week, however, clearing and warmer temperatures are expected for the Fourth of July weekend.
A trough of low pressure will move through the Central Coast on Sunday into Monday producing a deeper marine layer with areas of heavy drizzle during overnight and morning and cooler temperatures. In fact, the maximum temperatures will only reach the 70s in the inland areas (Paso Robles) and 60s in the coastal valleys (San Luis Obispo). The beaches will range from the high 50s to the low 60s. This system will continue to produce gentle to moderate (8 to 18 mph) northwesterly winds along the coastline, however, fresh to strong (19 to 31 mph) southwesterly winds are expected in the inland valleys.
A warming trend will develop on Tuesday through the Fourth of July weekend with temperatures reaching above normal as a ridge of high pressure builds over the Central Coast. Nevertheless, a persistent marine layer will remain along the shoreline with areas of fog and mist through Friday morning.
After days of gentle to moderate winds along the coastline, fresh to strong (19 to 31 mph) afternoon northwesterly winds are forecast to start on Friday and will continue through the Fourth of July weekend. These winds will produce clearing along the beaches during the afternoon and evening.
Seawater temperatures will range between 57 and 61 degrees on Sunday through Friday, deceasing next Saturday and Sunday.

PG&E safety tip
This week’s Southern Hemisphere swell could produce strong rip currents. These are generally narrow and swift-moving streams of water that flow from the beach, through the breaker zone, out to sea, then fan out behind the breakers and become quite diffused. If you find yourself in a rip current, swim parallel to the beach until you are out of the rip. Never try to swim against a rip, as you could become quickly tired and hypothermic in the cold waters of the Central Coast.
