Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
Monday morning’s northerly winds along the coastline are forecast to keep most of the coastal stratus clouds out to sea. Strong to gale-force (25- to 38-mph) northwesterly winds Monday afternoon should scour out the marine layer, resulting in mostly clear skies throughout the Central Coast. Monday’s high temperatures will reach the mid-80s in the North County and the mid- to high 70s in the coastal valleys. The beaches are predicted to remain in the 60s, except for the southwesterly facing beaches of Cayucos, Avila Beach and Shell Beach, which could reach the low 70s.
Marine low clouds with pockets of fog, mist and drizzle are predicted to develop in the coastal region of San Luis Obispo and Santa Barbara counties Tuesday into Wednesday, with limited clearing along the coastline during the afternoon hours as an area of low pressure moves southward east of the Central Coast. This low pressure system should also produce gentle to moderate (8- to 18-mph) northwesterly winds and rain showers across the southern Sierra Nevada. Maximum temperatures along the Central Coast should reach the mid-80s in the North County and high 70s in the coastal valleys away from the marine low clouds.
An upper-level low pressure system is forecast to move southward along the California coastline Thursday into the weekend. This system will produce strong to gale-force (25- to 38-mph) northwesterly winds and partly cloudy skies with areas of night and morning coastal low clouds. This system should produce a significant temperature drop across the North County with afternoon highs only reaching the mid 70s. This system is also predicted to produce some showers in the Sierra Nevada on Thursday night into Friday, with snow levels down to 5,000 feet and continued snow showers expected in the higher terrain into Saturday. The low-pressure system is expected to move eastward by late Sunday, but another weak low-pressure system is forecast to move into the Central Coast on its heels to keep temperatures seasonable or slightly cooler than normal through the middle part of next week.
Monday’s Surf Report
Strong to gale-force (25- to 38-mph) northwesterly winds will generate a 6- to 8-foot northwesterly (310-degree, deep-water) sea and swell (with a 4- to 12-second period) Monday into Tuesday, decreasing to 4 to 6 feet (with an 8- to 11-second period) Wednesday. Increasing northwesterly winds will drive up the northwesterly (305-degree, deep-water) sea and swell to 8 to 10 feet (with a 4- to 14-second period) Thursday, decreasing to 7 to 9 feet (with a 5- to 11-second period) Friday, further lowering to 4 to 6 feet with the same period this weekend. Arriving from the Southern Hemisphere: A 1- to 2-foot Southern Hemisphere (195-degree, deep-water) swell (with a 14- to 18-second period) is expected along our coastline Monday into Thursday.
Seawater temperatures are predicted to range between 53 and 56 degrees through Saturday.
