This week’s weather forecast by PG&E meteorologist John Lindsey.
A 1,029-millibar surface high over the Great Basin will produced gentle to moderate (8- to 18-mph) and at times gusty Santa Lucia northeasterly (offshore) winds during the night and morning hours through Wednesday. This offshore flow will produce clear skies and warm conditions throughout San Luis Obispo County.
Today’s maximum temperatures along the beaches will reach the 70s, while the coastal valleys and North County will hit the low 80s. Slightly warmer temperatures are expected on Tuesday and Wednesday.
Never miss a local story.
Note: The exceptionally dry vegetation throughout the Central Coast combined with these gusty Santa Lucia winds will produce high fire danger.

The area of high pressure responsible for the warm temperatures will move toward the east, while a weak upper-level trough will approach from the Pacific. This condition will cause the predominant wind flow to turn onshore by Thursday and will allow the marine layer to redevelop along the coast, which will produce night and morning low clouds and fog and cooler temperatures through the weekend.
The long-range charts and models are indicating that the storm track will remain far to the north for an extended period, keeping the Central Coast dry.
Today’s 3- to 5-foot northwesterly (305-degree deep-water) swell (with an 8- to 13-second period) will remain at this height and period through Thursday, decreasing to 2 to 3 feet (with a 7- to 11-second period) Friday through Sunday.
Typhoon Wipha off the coast of Japan is expected to become extratropical as it moves into the Northern Pacific. A long-period swell from the storm is expected to arrive along our coast Oct. 21-22.
Seawater temperatures will range between 55 and 58 degrees through Saturday.
