Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
An upper-level low will slowly drift past San Luis Obispo County as it descends toward the Southern California bight. This system will produce decreasing northwesterly winds, lower temperatures and a stubbornly persistent marine layer with pockets of night and morning mist and drizzle along the coastal regions through Wednesday.
Maximum temperatures in the North County will reach the low 90s, while the coastal valleys will reach the high 70s. The beaches will remain in the 60s. Temperatures will gradually start to rise by Thursday, as the low-pressure system moves out to sea and away from the coast.
Near-normal temperatures will likely continue into next weekend as an upper-level trough is expected to swing through the Pacific Northwest prolonging the cool northwesterly flow across the Central Coast with daily morning low clouds and fog expected along the coast.
Increasing northwesterly winds will generate a 3- to 5-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 12-second period) this afternoon.
A 2- to 4-foot (300-degree, deep-water) swell (with a 7- to 11-second period) will develop along our coastline Tuesday and will remain at this height and period through Sunday.
Today’s 1- to 2-foot Southern Hemisphere (195-degree, deep-water) swell (with a 15- to 17-second period) will gradually decrease over the next 24 hours.
A 1- to 2-foot Southern Hemisphere (210-degree, deep-water) swell (with an 18- to 20-second period) will arrive along our coastline Saturday and will peak Sunday at 1 to 3 feet (with a 15- to 17-second period).
Seawater temperatures are forecast to range from 57 to 62 degrees through Saturday.
