Here is this week’s weather forecast from PG&E meteorologist John Lindsey.
A fast-moving cold front produced between a quarter- and half-inch of rain in most Central Coast locations Sunday.
The Walter Ranch above Cambria reported the most precipitation, with more than sixth-tenths of an inch of badly needed rain.
A strong 1,033 millibar area of high pressure moved in behind Sunday’s cold front and produced a steep pressure gradient along the California coastline.
This pressure gradient created moderate gale-force to fresh gale-force (32 to 46 mph with gusts to 55 mph) northwesterly winds along the shoreline Sunday evening into Monday morning.
The northwesterly winds will decrease to strong to gale-force (25 to 38 mph) levels Monday afternoon. These winds will give lower seawater temperatures, partly cloudy skies and below average seasonal air temperatures.
High pressure will rebuild over California, which will produce fresh to strong (19 to 31 mph) night and morning Santa Lucia (northeasterly) winds starting Tuesday and continuing through Saturday. These northeasterly winds may be especially gusty Wednesday.
Overall, the Santa Lucia winds will produce dry, clear and gradually higher temperatures through the week. Long-range models then hint at the possibility of wet weather Sunday as a relatively weak weather system drops into the Central Coast from the north. However, details remain unclear.
Monday’s surf report
Moderate gale-force to fresh gale-force (32 to 46 mph) northwesterly winds along the California coast generated 13- to 15-foot northwesterly (320-degree, deep-water) sea and swell (with a 5- to 13-second period) along our coastline Sunday night into Monday morning.
This northwesterly sea and swell will decrease to 10 to 12 feet (with a 7- to 12-second period) Monday afternoon and night, further lowering to 7 to 9 feet (7- to 11-second period) by Tuesday.
A 5- to 7-foot northwesterly (310-degree, deep-water) swell (with an 8- to 12-second period) is forecast along our coastline Wednesday into Friday.
Seawater temperatures will range between 54 and 58 degrees through Tuesday, increasing to 57 and 60 degrees Wednesday into Friday.

At PG&E, your safety is our first concern. Are you ready for Monday’s winds? Here are some tips for preparing for power outages from PG&E:
▪ Have battery-operated flashlights with fresh batteries on hand. Please don’t use wax candles.
▪ Have battery-operated radios with fresh batteries ready for updates on storm conditions and outage updates.
▪ Freeze plastic containers filled with water to make blocks of ice that can be placed in your refrigerator and freezer during an outage to prevent food from spoiling.
▪ Secure or put away any outside items that can be blown by high winds into overhead power lines.
▪ Treat all downed power lines as if they are “live” or energized. Keep yourself and others away from them. Call 911, then notify PG&E at 800-743-5002.
