Posted
and last updated

Expect the San Diego special as we enter a new season: 70s and sunny! Temperatures will stay cool around the county over the next seven days, with temperatures this weekend below seasonal averages. While the coastline will reach into the low 70s over the weekend, expect inland neighborhoods to see mid 70s to low 80s.

The mountains and deserts will remain relatively warm over the weekend due to a ridge of high pressure to our east, but by Wednesday temperatures will dip three to five degrees below seasonal averages.

The autumn equinox takes place at 11:50 Pacific Time on September 22.

Saturday's Highs:
Coast: 70-78
Inland: 75-83
Mountains: 76-85
Deserts: 95-101
