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

Weather Report

A weak upper-level low-pressure system is forecast to migrate eastward across California on Monday with increasing marine low clouds and lower temperatures. Pockets of mist and drizzle should develop during the night and morning hours in the coastal regions of San Luis Obispo and Santa Barbara counties. The marine low clouds will clear back to the immediate shoreline during the afternoon hours, with a few of the beaches remaining overcast for most of day.

Monday’s high temperatures are projected to range between the 60s at the beaches to low 70s in the coastal valleys and 80s further inland. Thunderstorm chances increase in the Sierra Nevada. Because of limited moisture associated with the upper-level low, little to no precipitation is expected with these thunderstorms, but there is a possibility of dry lightning.

The northwesterly (onshore) winds are forecast to increase Tuesday to fresh to strong (19- to 31-mph) levels, further building to strong to gale-force (25- to 38-mph) levels along the shoreline Wednesday. These winds should produce night and morning low clouds with pockets of mist and drizzle along the coastline; however, they will also produce increasing amounts of sunshine along the beaches during the afternoon hours. These onshore winds are also forecast to produce near-normal June temperatures throughout the Central Coast. Moderate gale-force to fresh gale-force (32- to 46-mph) northwesterly winds may develop Thursday into Saturday along the coastline. If these winds develope as advertised, they should be strong enough to mix out the marine layer, leaving behind mostly clear and sunny skies starting Thursday and continuing through the weekend.

Surf Report

Monday’s 2- to 4-foot northwesterly (310-degree, deep-water) swell (with a 7- to 11-second period) should remain at this height and period through Tuesday. Strong to gale-force (25- to 38-mph) northwesterly winds along the California coastline will generate a 4- to 6-foot northwesterly sea and swell (with a 5- to 9-second period) Wednesday into Thursday. This northwesterly sea and swell should further build to 8 to 10 feet (with a 7- to 11-second period) Friday through Saturday.

A 1- to 2-foot Southern Hemisphere (210-degree, deep-water) swell (with an 18- to 20-second period) is forecast to arrive Sunday, building to 2 to 3 feet (with a 15- to 17-second period) next Monday and Tuesday.

Seawater temperatures

Seawater temperatures are projected to range between 55 and 59 degrees through Wednesday, decreasing to 51 and 56 degrees on Thursday into Saturday.
