San Diego rolled out of bed to a cool, gray start today with coastal spots stuck in the mid‑60s under a stubborn blanket of low clouds hugging the shoreline. The gloom will not last. Forecasters expect the marine layer to thin by late morning, clearing to mostly sunny skies and a high near 73°F this afternoon, with a light northwest breeze around 5 to 10 mph.
Afternoon Outlook
High pressure building to the east will steadily nudge temperatures upward through midweek, pushing inland highs into the mid‑70s and making it hotter in the desert valleys. That setup brings a localized heat risk for deserts and some lower mountain slopes tomorrow and Wednesday, according to the National Weather Service San Diego.
Foggy Mornings, Sunny Afternoons
Night and morning, low clouds will keep the coast and nearby valleys on the cool side, then back off late in the morning, roughly between 10 and 11 AM, for sunnier afternoons. Inland neighborhoods will shake off the clouds earlier and end the day a few degrees warmer than the immediate coast.
Beaches and Rip Currents
A long‑period southerly swell will bump up surf a bit this week and raise the risk of strong rip currents at many beaches, the National Weather Service San Diego warns. If you are heading into the water, swim near a lifeguard and check local conditions first.
What To Bring
No watches or warnings are in effect for the immediate coastal area. If you are going inland or into the desert tomorrow or Wednesday, bring plenty of water, try to schedule outdoor plans outside the hottest part of the day, and keep an eye on local forecasts. For a break from hotter inland afternoons, San Diego County maintains air‑conditioned “Cool Zones” and other resources. Call 2‑1‑1 or visit San Diego County Cool Zones for locations.
