Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
If it wasn’t for the shortness of the days, one would think that it’s summer. Sunday’s high temperatures reached record levels. The San Luis Obispo County Airport reported 85 degrees; the record was 80 degrees set in 2014. Paso Robles hit 77 degrees, breaking the record of 76 degrees, also set last year. Los Osos, Morro Bay and Cayucos all reached 83 degrees.
The ridge of high pressure responsible for the record-high temperatures will move to the east and a closed, upper-level low-pressure system near Baja will travel northward
toward the Central Coast. This system is more reminiscent of a summer storm than that of winter.
This upper-level low will draw subtropical moisture from the south today with increasing clouds and lower temperatures, and rain showers over the elevated terrain later today. As this tempest travels farther north Tuesday, more widespread rain will develop across San Luis Obispo County. Because of the subtropical nature of the system, snow levels will remain above 7,000 feet in the Sierra Nevada. Total rainfall amounts will range around a quarter of an inch.
Santa Lucia (northeasterly) winds will produce a dry and clear Wednesday. Increasing northwesterly winds Thursday and Friday will produce areas of marine low clouds along the coastline and mild temperatures. Another round of Santa Lucia winds will produce clear and warm conditions this weekend. The next chance of rain appears to be Feb. 4.
Today’s 5- to 7-foot northwesterly (300-degree, deep-water) swell (with a 14- to 16-second period) will lower to 4 to 6 feet (with a 13- to 15-second period) Tuesday. This northwesterly (300-degree, deep-water) swell will further lower to 3 to 5 feet (with a 12- to
14-second period) Wednesday into Thursday morning.
Increasing northwesterly winds will generate 4- to 6-foot (310-degree, deep-water) sea and swell (with a 5- to 17-second period) Thursday afternoon into Saturday.
Seawater temperatures will range between 58 and 60 degrees through Thursday, decreasing Friday.

PG&E safety tip: Buckling up is such a simple thing to do; it only takes two seconds, and no other single action has as much lifesaving potential. If more adults wore safety belts, their kids would, too. Besides, it’s the law.
