San Diego woke up under a thick marine layer today, with cloudy skies and temperatures sitting near 63°F at Lindbergh Field. Low clouds and patchy fog are expected to cling to the coast and parts of the valleys through the morning, then thin or scatter by midday so beaches and inland neighborhoods can look forward to mostly sunny afternoons. Highs should reach around 70°F along the water, with inland areas warming up more as the week goes on.
Afternoon Differences
The coast and valleys will hold a few degrees cooler, while the mountains and deserts crank up the heat. Highs are forecast near 70°F at the beaches and in the low to mid 70s inland tomorrow and into Thursday. Out in the lower deserts, temperatures may jump into the 104–108°F range on Thursday. A low-pressure system is expected to move in and trigger a cooling trend from Friday through next Sunday, with night and morning low clouds pushing farther inland each night, according to the National Weather Service.
Timing and Commute
Morning low clouds will fill the coastal basin and higher inland valleys before scattering by mid to late morning, reducing visibility for early commuters, especially along corridors like I-8 and SR-52. West to northwest winds are expected to remain on the lighter side, generally 0–10 mph, with somewhat stronger gusts in the foothills and passes; no wind advisories are in effect. Drivers can check live road conditions and traffic cameras before heading out at Caltrans QuickMap.
No Advisories; Marine Outlook
There are currently no watches, warnings or advisories in effect for San Diego County, and no hazardous marine conditions are expected through Saturday. Anyone planning early-morning bay or beach time should factor in cool, foggy starts with a light jacket and then stronger sun for the warmer inland afternoons with sunscreen, according to the National Weather Service.
