Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
This morning’s extensive marine layer is forecast to slowly clear back to the coast during the morning hours and will give way to hazy afternoon skies.
Strong to gale-force (25- to 38-mph) northwesterly (onshore) winds along the coast and mild temperatures will develop this afternoon. Today’s maximum temperatures will range from the mid-60s in the coastal valleys to the mid-70s in the North County and inland valleys. High temperatures along the beaches will range from the high 50s to the low 60s.
Low clouds and fog will come rolling back in tonight into Tuesday morning, with pockets of mist and drizzle along the coast. Increasing northwesterly winds will help to scour out the marine layer and give way to mostly clear skies Tuesday afternoon.
The middle of the week will see a weak ridge of high pressure build over the region Wednesday under partly cloudy skies.
Unsettled weather is expected to return for the remainder of the week as a broad upper-level trough of low pressure develops off the coast and gradually moves eastward across the Central Coast, producing gentle to moderate (8- to 18-mph) southerly winds, increasing clouds and lower temperatures Thursday and a chance for widespread rain showers, thunderstorms and even snow across the higher elevations Friday into Saturday.
Increasing northwesterly winds along the California coastline will generate a 7- to 9-foot northwesterly (305-degree, deep-water) sea and swell (with a 5- to 11-second period) today through Tuesday. This northwesterly sea and swell will decrease to 4 to 6 feet Wednesday, becoming a 3- to 5-foot northwesterly (295-degree, deep-water) swell (with an 8- to 12-second period) Thursday into Friday.
Arriving from the Southern Hemisphere
A 1- to 2-foot Southern Hemisphere (190-degree, deep-water) swell (with a 16- to 22-second period) is expected to arrive along our coastline Tuesday, gradually building to
2 to 3 feet (with a 16- to 18-second period) Thursday into Friday.
Seawater temperatures will range between 51 and 54 degrees through Wednesday, increasing to 53 and 57 degrees Thursday into Saturday.
