Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
Gale force northwesterly (onshore) winds along the coastline during the afternoon will continue to produce below normal temperatures throughout San Luis Obispo County. Highs along the coastline will range from the mid- 50s to low 60s along the northwesterly facing beaches (Morro Bay, Los Osos, Montaña De Oro and the Nipomo Mesa); the low 60s along the westerly facing beaches (Pismo Beach and Cambria); and the high 60s along the southwesterly facing beaches (Cayucos, Avila and Shell beaches). Overall, it looks like breezy, clear and mild weather for the “Lost at Sea memorial at the Cayucos Pier” at 3 p.m. The coastal valleys will reach the low 70s and the North County is expected to hit the low 80s.
A late season cold front will produce increasing clouds and patchy fog and drizzle tonight into Tuesday morning. This system is expected to produce rain as far south Monterey Bay by late this evening. This is a relatively warm low-pressure system and snow levels are expected to remain above 7,500 feet with only a light dusting expected across the higher elevations of the Sierra Nevada Mountains and Tehachapi Range.
A ridge of high pressure will start to build over the Central Coast on Wednesday. This condition will produce a warming trend on Thursday into Sunday. Northeasterly (Santa Lucia) winds with above-normal temperatures and low relative humidity levels will be possible by the weekend.
Moderate gale to fresh gale-force (32- to 46-mph) northwesterly winds during the afternoon hours will continue to generate a 4- to 6-foot northwesterly (310-degree deep-water) sea and swell (with a 5- to 12-second period) through Wednesday.
These northwesterly winds will build along the entire coastline of California later on Wednesday. Consequently, the northwesterly (310-degree deep-water) sea and swell will increase to 8 to 10 feet (with a 7- to 11-second period) on Thursday and will remain at this height and period through Friday.
A 5- to 7-foot northwesterly (295-degree deep-water) swell (with an 8- to 11-second period) is forecast along our coastline Saturday, decreasing to 4 to 6 feet Sunday.
Arriving from the Southern Hemisphere:
A 1- to 2-foot Southern Hemisphere (200-degree deep-water) swell (with a 16- to 18-second period) is expected along our coastline today, decreasing Tuesday.
Seawater temperatures will range between 48 and 51 degrees through Friday, increasing to 51 and 54 degrees over the weekend.
