Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
A 1,020-millibar area of high pressure off the California coast, combined with a thermal low over the Central Valley, will produce strong to gale-force (25- to 38-mph) northwesterly (onshore) winds during afternoons along the shoreline. These onshore winds will continue to produce night and morning low clouds with areas of fog and drizzle. These clouds will clear from the coastal valleys during the late morning and from the beaches in the afternoon.
Maximum temperatures will be in the 60s along northwesterly facing beaches (Morro Bay, Los Osos, Montaña De Oro and the Nipomo Mesa) and the westerly facing beaches (Pismo Beach, Grover Beach and Cambria). Southwesterly facing beaches (Cayucos, Avila Beach and Shell Beach) will reach the low 70s. Coastal valleys will hit the high 70s, with mid-90s across the North County.
Warmer weather, at least away from the coast, is expected next week. Overall, the weather over the next week to 10 days will be rather benign and typical of mid/late summer in California, with no heat waves or rain expected in the next two to three weeks.
Strong to gale force (25- to 38-mph) afternoon northwesterly winds will generate a pattern of 4- to 6-foot northwesterly (325-degree shallow-water) seas (with a 3- to 5-second period) during the afternoon, decreasing to 3 to 5 feet during the night and morning hours. This pattern will continue through Saturday.
Seawater temperatures will be between 52 and 55 degrees through Saturday.
