San Diego woke up today under a stubborn marine layer, with cloudy skies and temperatures hovering near 66°F at San Diego International Airport. The gray should thin to partly sunny skies by midday, letting coastal spots warm into the low 70s, with a high near 73°F this afternoon. Light northwest breezes will keep the bayfront feeling comfortable, and overnight lows are expected to slip back to about 64°F.
Forecast Details
Low clouds are expected to thin and pull back by midday, leaving most neighborhoods under partly sunny skies, while the immediate shoreline holds onto cooler conditions. Tomorrow, Independence Day, is shaping up almost the same: partly sunny with a high near 74°F. A weak upper-level disturbance could toss in some higher clouds and even a stray late-afternoon shower over the county mountains, but that is about as dramatic as it gets. A gradual warming trend builds through the middle of next week, especially inland, with temperatures climbing in interior valleys and in the deserts. This forecast comes from the National Weather Service San Diego.
Coastal Fog And Commute
Morning fog and low clouds will cling to the shoreline and may trim visibility on some coastal routes through late morning, while inland areas clear out faster and see sunshine sooner. The sea breeze will keep beaches and the bayfront on the cool side, and neighborhoods just a few miles inland will feel noticeably warmer as the day goes on. If you are heading out early for fireworks plans or other events, it is worth giving yourself some extra time for slower traffic and patches of murky visibility along shore routes.
Next Week And Heat Safety
Temperatures tick upward into next week, and the low deserts could see moderate to high heat risk from next Tuesday through Friday, so plan for plenty of water, access to shade and shorter outdoor stretches if you are traveling inland. For anyone sensitive to heat, the San Diego County Cool Zones list air-conditioned locations where residents can find relief. There are no watches or warnings in effect for coastal San Diego at this time, but anyone heading inland or out to the deserts should keep an eye on the latest forecasts if you will be spending time away from the coast.
