Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
Increasing high pressure over California is expected to produce night and morning Santa Lucia (northeasterly) winds. These winds will produce mostly clear skies, including at the beaches, and gradually warmer temperatures through Wednesday. Increasing northwesterly winds during the afternoon hours will keep temperatures from warming up too much.
Monday’s high temperatures are expected to reach the mid-70s in the North County and coastal valleys. High temperatures along the beaches will range from the high 60s along the northwesterly facing beaches of Morro Bay, Los Osos, Montaña de Oro and Nipomo, and the low 70s along the westerly facing beaches of Cambria, Grover Beach and Pismo Beach. Southwesterly facing beaches, like Cayucos and Avila Beach, will be in the mid-70s.
Night and morning marine low clouds will return along the coast Wednesday night into Sunday, as the winds blow out of the northwest on a consistent basis.

The numerical weather models are hinting that rain may finally come to the coastal regions of San Luis Obispo and northern Santa Barbara counties. A low-pressure system is forecast to move into Northern California on Tuesday or Wednesday next week, which may produce some widespread rain showers for the Central Coast. That system could be followed by another, stronger low-pressure system toward the end of next week that may produce continued unsettled weather across the Central Coast into the following weekend.
Monday’s surf report
Monday’s 6- to 8-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 12-second period) will decrease to 4 to 6 feet (with a 7- to 11-second period) Tuesday into Wednesday.
A 5- to 7-foot northwesterly (300-degree, deep-water) swell (with an 8- to 17-second period) will arrive along our coastline Thursday, building to 6 to 8 feet (with an 8- to 15-second period) Friday into Saturday. An 8- to 10-foot west-northwesterly (285-degree, deep-water) swell (with a 17- to 19-second period) is forecast to arrive on the Central Coast on Oct. 26.
Arriving from the Southern Hemisphere
A 1- to 2-foot Southern Hemisphere (210-degree, deep-water) swell (with a 15- to 17-second period) is expected to arrive Monday and will remain at this height and period through Friday. A very long period Southern Hemisphere swell is expected along our coastline Sunday.
Seawater temperatures will range between 61 and 64 degrees through Monday, decreasing to 59 and 63 degrees Tuesday into Thursday.

At PG&E, your safety is our first concern. If it rains next week, be especially careful. After a long dry period, the first rain releases oil and grease that has accumulated on roadways, creating slippery conditions. Please slow down and give yourself extra time to reach your destination. Driving too fast is the No. 1 cause of accidents on wet days.
