The upper-level low-pressure system that brought a cold air mass from Canada and produced freezing nighttime temperatures moved eastward from California.

High pressure will build behind it and push the jet stream north, allowing warmer temperatures to develop Sunday through Tuesday.

During this period, a pattern of moderate to cool winds (13-24 mph) from Santa Lucia (northeast/offshore) will develop overnight and into the morning, shifting from the northwest (onshore) and becoming cool at strong (19 to 31 mph) levels during the afternoon with high temperatures reaching the 70s across the central coast by Sunday. Temperatures will continue to warm into the mid-70s on Monday and Tuesday.

Persistent northwesterly winds (overland) Wednesday through Saturday will allow the marine layer to expand in coastal regions overnight and into the morning with patches of fog and haze and produce cooler temperatures. Northwest winds could reach moderate levels of gale to fresh gales (32 to 46 mph) along the coast Thursday through Friday.

surf report

A 954 millibar storm off the Kamchatka Peninsula last Wednesday generated a long period west-northwesterly swell train (290 degrees, in deep water). This long period swell will reach 6 to 8 feet (with a period of 17 to 19 seconds) from Sunday to Tuesday.

Increasing northwesterly winds will produce 6 to 8 foot northwest (300 degrees, deep water) sea and swell (with a period of 7 to 15 seconds) on Wednesday, rising to 8 to 10 feet Thursday in Friday.

Sea water temperatures will fluctuate between 52 and 54 degrees until Friday.

PG&E Security Council

The long period swell expected to arrive along the central coast from Saturday to Monday can create ‘rogue’ or ‘sneaker’ waves. Sneaker waves are deadly, larger than average swells that can suddenly and without warning surge dozens of feet higher than expected on the beach, overtaking the unwary. They can smash rocks and lift logs onto the beach with deadly force.

The message is simple but important: when you’re near the waves, NEVER TURN YOUR BACK ON THE OCEAN.
