Most of California is cooling down by about five to 12 degrees Monday as offshore trends switch to onshore.

The beaches will range from the upper 60s to the low 70s and the coastal valley regions will mostly stay close to the mid-70s Monday. The inland valleys are also cooling down and will have temperatures from the mid-80s to the low 90s. Some stratus will develop for the coastline and coastal valleys Monday morning along the Central Coast, while the coastline in Santa Barbara could experience some patchy fog.

Breezy conditions will remain in the forecast Monday with sustaining winds from 10-15 miles per hour and wind gusts from 20-25 mph. Wind models are showing the breezy conditions will continue well into Monday night and will start to taper off close to 4:00 a.m. Tuesday.

Temperatures will start to warm up again Tuesday and Wednesday as offshore flow redevelops. From Tuesday to Wednesday, peak temperatures are expected to increase by at least ten degrees for much of the region before cooling down again by the end of the week. Rain is a possibility this week from Wednesday night through Saturday as an an upper trough develops over the southwestern portion of California.
