Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
The week’s weather will be characterized by plenty of low clouds and fog during the night and morning hours and below normal-seasonal temperatures.
A 1,006-millibar low pressure system will remain nearly stationary over our area through Tuesday morning. This system will produce gentle to moderate (8- to 18-mph) southerly winds and a deepening marine layer. As the system moves further southward and the Eastern Pacific High builds in behind it, strong to gale-force (25- to 38-mph) northwesterly winds will develop along the coastline Tuesday and Wednesday afternoon. These winds will produce a greater amount of clearing along the beaches and will further help to spread cool and moist marine air throughout San Luis Obispo and Santa Barbara counties.
An upper-level trough is expected to pass over the Central Coast on Thursday into Friday, with increasing clouds and extensive night and morning marine stratus, fog and drizzle and even a chance of light rain showers; in other words, a bit gloomy. This system will also encourage thunderstorm and rain shower development across the Sierras with scattered showers possible across the foothills through Saturday. Warmer and sunnier weather is forecast to start Sunday into next week.
Today’s surf report
Today’s 3- to 5-foot northwesterly (295-degree, deep-water) swell (with an 8- to 11-second period) will continue through tonight.
Increasing northwesterly winds along the California coastline will generate an 8- to 10-foot northwesterly (305-degree, deep-water) sea and swell (with a 5- to 11-second period) Tuesday through Thursday. This northwesterly sea and swell will decrease to 4 to 6 feet Friday, further lowering to 3 to 5 feet with the same period Saturday into Sunday.
Arriving from the Southern Hemisphere
Today’s 4- to 6-foot Southern Hemisphere (190-degree, deep-water) swell (with a 15- to 20-second period) with occasional sets of waves of 5 to 7 feet will gradually decrease Tuesday into Wednesday.
Wave heights across the favored south facing beaches in the Southern California Bight could reach well over 10 feet. Overall, this is one of the larger Southern Hemisphere swells over the past few years.
Seawater temperatures will range between 52 and 56 degrees through Tuesday, decreasing to 51 and 54 degrees Thursday into Sunday.

At PG&E, your safety is our first concern. Long-period Southern Hemisphere swells can produce strong rip currents along many of our beaches. Never turn your back to the ocean as sneaker waves can inundate beaches and pull people into the water.
