Valencia Peak was shrouded in fog Saturday.

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

Much like last week, the Eastern Pacific High will remain anchored about 600 miles to the west of San Luis Obispo, while a thermal trough remains centered over the Great Central Valley of California. This pattern will produce strong to gale-force (25 to 38 mph) northwesterly winds along the coastline during the afternoon hours, night and morning marine low clouds and fog in the coastal regions and seasonal temperatures.

The North County will hit the mid-90s, while the coastal valleys will reach the high 70s. Temperatures will range between the high 50s and low 60s at the shoreline, except for the southwesterly facing beaches of Cayucos and Avila Beach, which will hit the low 70s.

Cooler weather develops Tuesday into Friday morning as a trough of low pressure develops off the West Coast. This system will produce decreasing northwesterly winds, extensive night and morning coastal low clouds, with areas of fog and drizzle and a chance of a few rain showers Thursday night into Friday morning.

In the system’s wake, moderate gale-force to fresh gale-force (32 to 46 mph) northwesterly winds will develop along the coastline Friday afternoon into Saturday.

Surf report

A 7- to 9-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 11-second period) is forecast along our coastline into Monday.

A 6- to 8-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 11-second period) is forecast along our coastline on Tuesday, decreasing to 4 to 6 feet with the same period Wednesday. This northwesterly sea and swell will further lower to 3 to 5 feet (with a 5- to 11-second period) on Thursday into Friday morning.

Increasing northwesterly winds will generate 5- to 7-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 12-second period) Friday afternoon into Saturday.

Arriving from the Southern Hemisphere: Monday’s 1- to 3-foot Southern Hemisphere (190-degree, deep) swell (with a 15- to 17-second period) is forecast to continue at this height and period through Wednesday.

Seawater temperatures

Seawater temperatures will range between 50 and 52 degrees through Saturday. A southerly (offshore) flowing current will continue to flow southward into Saturday.
