Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
An upper-level area of low pressure along the West Coast is expected to hold through this week. This condition will continue to produce night and morning marine low clouds with pockets of mist and drizzle and slightly below normal temperatures through Friday. In fact, most of San Luis Obispo County’s beaches may remain overcast throughout the day Tuesday into Wednesday.
Monday’s high temperatures are forecast to range from the mid-90s in the North County to the low 80s in the coastal valleys. The beaches will continue to range from the high 50s to the mid-60s.
This week, surface winds are expected to continue to blow out of the northwest, which will bring in variable amounts of smoke from the 58,000-acre Soberanes Fire in Monterey County. The greatest amounts of smoke will likely come in the morning, dispersing during the afternoon. This condition will produce an odd combination of smoke and fog along the beaches and coastal and inland valleys in the morning hours.

Overall, only subtle daily variations will continue through Friday; however, the longer-range models advertise higher temperatures on Saturday as high pressure briefly builds over California, but a trailing low-pressure system should keep any heat short-lived.
Sunday’s 4- to 6-foot northwesterly (325-degree, deep-water) sea and swell (with a 5- to 10-second period) will remain at this height and period through Monday morning, increasing to 5 to 7 feet (with a 7- to 11-second period) Monday afternoon into Wednesday. This northwesterly sea and swell is expected to decrease to 4 to 6 feet (with a 7- to 11-second period) on Thursday, further decreasing to 3 to 5 feet (with an 8 to 17-second period) Friday into Saturday.
Seawater temperatures are projected to range between 54 and 57 degrees through Friday.
