Here is this week’s weather forecast by PG&E meteorologist John Lindsey:
Warm conditions should develop today in the North County as a ridge of high pressure shifts eastward over San Luis Obispo County. Along the coastal regions, the marine layer is expected to produce night and morning low clouds and fog and cooler daytime conditions.
Today’s maximum temperatures should reach the mid-90s in Paso Robles, the high 70s in San Luis Obispo and 60s along the beaches. Overall, it looks like beautiful conditions in Cayucos for the Lost at Sea Memorial at 3 p.m.

A trough of low pressure is forecast to develop off the coast Tuesday and should remain stationary through Friday. This low pressure is expected to produce strong to gale-force (25- to 38-mph) afternoon northwesterly winds along the coastline and night and morning marine low clouds and fog. The cooler marine air should filter through the coastal gaps and passes into the North County and bring cooler afternoon temperatures.
Temperatures should remain near-normal through the weekend, with fair and dry conditions continuing across the Central Coast into the first week of June.
Today’s 5- to 7-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 11-second period) will increase to 6 to 8 feet (with a 5- to 9-second period) Tuesday.
Near storm-force northwesterly winds about 100 miles out to sea will generate 8- to 10-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 10-second period) Wednesday into Thursday.
A 5- to 7-foot northwesterly (300-degree, deep-water) sea and swell (with a 5- to 9-second period) will develop along our coastline Friday, decreasing to 4 to 6 feet with the same period Saturday.
A 1-foot Southern Hemisphere (210-degree, deep-water) swell (with an 18- to 20-second period) will arrive along our coastline Tuesday, building to 2 to 3 feet (with a 16- to 18-second period) Wednesday.
Seawater temperatures are expected to range from 51 to 54 degrees through Saturday.
