Here is this week’s weather forecast by PG&E meteorologist John Lindsey.

Strong to gale-force (25- to 38-mph) winds are expected to continue to produce mostly clear skies Monday. Monday’s high temperatures will range from the high 90s in the North County and high 70s in the coastal valleys. The beaches will range from the low to mid-60s, except for the southwesterly facing beaches of Cayucos, Avila Beach and Shell Beach, which should reach the high 70s.

High pressure will build over the region Tuesday into Thursday, with increasing inland temperatures. The North County is expected to range between the high 90s and the low 100s on Tuesday into Thursday. Along the coastline, marine low clouds with pockets of mist and drizzle during the night and morning hours will keep temperatures in the 70s in the coastal valleys and 60s along the beaches.

Cooler weather is expected Friday into Sunday, as the high-pressure ridge breaks down in response to a low-pressure system moving across far Northern California. Temperatures are set to decrease back to normal or even slightly below normal under a deep marine layer, with periods of fog and drizzle during the night and morning hours. The high-pressure ridge should then rebuild across California over the following week for warmer weather, especially in the North County where temperatures may get above 100 degrees for the Mid-State Fair, which begins July 20.

Surf report

Increasing northwesterly winds are expected to produce 6- to 8-foot northwesterly (320-degree, shallow-water) seas (with a 5- to 7-second period) on Monday. A 4- to 6-foot northwesterly (315-degree, deep-water) sea and swell (with a 5- to 9-second period) is forecast along the San Luis Obispo County coastline Tuesday into Thursday, increasing to 6 to 8 feet (with a 7- to 11-second period) Friday into Sunday.

Arriving from the south: Monday’s 2- to 3-foot southerly (205-degree, deep-water) swell (with a 10- to 12-second period) from former Hurricane Blas will decrease. Tropical Storm Celia is expected to strengthen over the next 48 hours and become a hurricane. A 1- to 2-foot southerly (210-degree, deep-water) swell from this tropical cyclone is forecast to arrive along the Central Coast on Thursday into Friday.
