Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
The upper-level low-pressure system that brought unsettled weather to Northern California and the Sierra Mountains has moved to the east, and the eastern Pacific high will build from the west. This condition will bring mostly clear skies and warmer conditions.
Gentle to moderate (8- to 18-mph) Santa Lucia (offshore) winds during the morning hours will keep the marine layer out at sea, and strong to gale-force (25- to 38-mph) northwesterly (onshore) winds during the afternoon hours will keep temperatures mild throughout San Luis Obispo County today and Tuesday.
Today’s high temperatures will reach the mid-80s in the North County and mid-70s in the coastal valleys. The beaches will remain in the 60s, except the southwesterly facing beaches of Cayucos, Avila Beach and Shell Beach, which will reach the 70s.
Never miss a local story.
Maximum temperatures will gradually warm and by Friday will be above normal; however, no extreme heat is anticipated at this time. Long-range forecast models suggest that the warm and dry weather will persist through next weekend into the first full week in October with no precipitation on the horizon. PG&E Safety Tip: During periods of dry and warm weather, always remember to stay hydrated.
