Santa Lucia (northeasterly) winds during the morning hours will keep most of the marine layer out to sea, while strong to gale-force (25 to 38 mph) afternoon northwesterly winds along the shoreline will keep temperatures mild. This pattern will continue through the first half of this week.

Autumn-like morning temperatures and gradually cooler conditions are forecast throughout San Luis Obispo and northern Santa Barbara Counties. In fact, temperatures should track below normal through Wednesday.

Sunday's high temperatures will reach mid 80s in the Santa Ynez Valley and mid 70s in the coastal valleys. High temperatures along the beaches will remain in the 60s.

Temperatures should return to near-normal over the last half of next week as the trough of low-pressure responsible for the cooler weather will shift off toward the northeast. In fact, after a few subtle days of warming, a more pronounced warming-trend could develop this weekend as strong high pressure builds. The building of high pressure from the eastern Pacific will likely encourage the development of offshore flow resulting in an in increase in fire danger.

This Week’s PG&E Safety Tips

At PG&E, the safety of our customers and employees is our top priority. According to CAL FIRE, nearly 90 percent of all wildfires in California are caused by people, often when they are engaged in routine activities. Tasks like mowing the lawn, using a weed eater or using a chain saw can spark a wildfire. Similarly, worn brakes, exposed wheel rims and dragging tow chains can also cause sparks and ignite a fire while driving. To lean more, please visit:
