San Luis Obispo County weather forecast for the week of March 30

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

So far, Paso Robles has broken the daily temperature record four days in a row and is forecast to reach 90 degrees this afternoon. If the North County community reaches 87 degrees, it will be the fifth consecutive day of record temperatures.

The best way to describe this week’s weather is windy. The ridge of high pressure responsible for these record-breaking temperatures will weaken today as an upper-level trough approaches the California coast. This condition will produce night and morning low clouds and fog, increasing northwesterly winds and cooler temperatures along the coast and coastal valleys. 

A weak cold front will pass over the Central Coast on Tuesday morning, followed by moderate gale-force to fresh gale-force northwesterly winds along the coastal regions and cooler temperatures throughout our region, including the interior valleys. As a strong 1,036-millibar eastern Pacific high nudges closer to the West Coast, the northwesterly winds will increase further Thursday. Windy indeed!  High pressure will then return Friday into Saturday for Santa Lucia (northeasterly) winds and warmer temperatures. 

Over the past few days, the numerical models have consistently advertised wet and unsettled weather for California, including San Luis Obispo and Santa Barbara counties early next week.  

Surf report

A prolonged period of gale-force northwesterly winds along the Northern and Central California coastline will produce rough oceanographic conditions this week. 

Today’s 7- to 9-foot northwesterly (305-degree, deep-water) sea and swell (with a 5- to

13-second period) will increase to 8- to 10-feet (with a 5- to 12-second period) Tuesday. This northwesterly sea and swell will further build to 10 to 12 feet (with a 5- to 15-second period) Wednesday into Thursday, and then gradually decrease Friday into Saturday.

Arriving from the Southern Hemisphere

Today’s 3- to 4-foot Southern Hemisphere (190-degree, deep-water) swell (with a 15- to

17-second period) will gradually decrease Tuesday into Wednesday.

Seawater temperatures

Seawater temperatures will range between 52 and 55 degrees through tonight, decreasing to 49 and 53 degrees Tuesday. Temperatures should remain at this level through Sunday.
