San Diego, CA – California’s southern coast wakes to a soft marine haze this Sunday morning as fall fog returns to the shoreline. The mild pattern will keep mornings gray and damp before sunshine breaks through by late morning — a classic setup for this time of year.
According to the National Weather Service in San Diego, calm winds and cooler air off the Pacific will allow patchy fog to form again Monday and Tuesday mornings. Visibility could briefly dip below a half mile along coastal highways and near the San Diego International Airport. Drivers on I-5 and State Route 163 should take it slow early in the commute hours, when fog is most likely to linger.
By late morning, the fog lifts to reveal bright, warm afternoons with highs near 78°F Monday and low 70s by Wednesday. Winds stay light, and humidity remains comfortable — ideal weather for outdoor events and late-season beach trips.
Midweek, cloud cover increases slightly as cooler air drifts inland, but no rain is expected through at least Friday. Forecasters say the pattern fits a typical October rhythm — mild, foggy mornings and steady sunshine to close out each day.
Looking toward the weekend, San Diego stays seasonably warm, with highs near 73°F and a light coastal breeze. It’s ideal fall weather for pumpkin patches, surf sessions, or simply savoring the calm before the early winter winds return.
