SAN DIEGO (KGTV) — A cooler stretch of September weather is settling into San Diego County, bringing a deeper marine layer, more morning clouds and below-average temperatures before a noticeable warm-up later this week.
Sunday begins with plenty of cloud cover across the coast and valleys, with patchy fog possible farther inland. Some clearing is expected as the day goes on, but temperatures will trend cooler across much of the county.
Highs will stay mainly in the 70s near the coast, while inland communities climb into the 80s. The mountains will also reach the 70s and 80s, with the hottest conditions remaining in the deserts.
Even cooler Monday
Another area of low pressure moving into California will deepen the marine layer heading into Monday…
