SAN DIEGO, Calif. – A silver-gray haze drifts inland from the Pacific this morning, softening the city skyline and dimming the early light across Mission Bay. The familiar November calm holds steady as patchy fog blankets coastal neighborhoods from La Jolla to Chula Vista — a tranquil start before a bright, mild stretch unfolds.

According to the National Weather Service in San Diego, the region stays quiet through midweek with fog lingering along the coast during early morning hours. Highs will climb into the lower 70s through Wednesday, with light winds and steady sunshine by afternoon. Skies will clear fastest inland, while beaches remain wrapped in haze until late morning.

Commuters along I-5 and coastal highways should expect reduced visibility during the early drive, especially through low-lying areas of Del Mar, Encinitas, and downtown. Drivers are urged to use low beams and slow down until the fog lifts. Air travel remains generally smooth, though slight delays are possible during peak morning departures at San Diego International Airport.

The pattern stays stable through Thursday before gradual clearing gives way to a cooler trend this weekend. Inland valleys could dip into the upper 50s by early morning Saturday, a reminder that even Southern California is sliding into late fall.

It’s a near-perfect stretch for outdoor plans, early holiday decorating, or beach walks — just keep an eye out for that morning mist rolling off the Pacific.
