San Diego started today wrapped in low clouds and patchy fog, with San Diego International Airport sitting at a sticky 63°F and the coast feeling more like a damp blanket than a beach postcard. The gloom should give way to sunshine by midday, with a comfortable afternoon near 72°F before a more serious warm-up pushes inland temperatures higher through next Monday.
Foggy Mornings, Sunny Afternoons
Patchy fog is expected along the immediate coast and into the lower coastal valleys through about 11 AM, occasionally cutting visibility and keeping spots near the bay cooler than neighborhoods just a few miles inland. As the marine layer thins late in the morning, skies turn partly sunny and highs land around 72°F at the coast and in the low 70s inland.
West winds stay generally light to moderate, around 0 to 10 mph, with slightly stronger afternoon gusts squeezing through mountain passes and gaps. Coastal residents get the classic gray-then-sun routine, while inland areas start to feel the early hints of the coming heat.
Heat Risk For Deserts And Inland Valleys
High pressure builds through next Monday, shrinking the marine layer and nudging inland highs into the mid to upper 70s, while the low deserts shoot into triple digits. According to the National Weather Service San Diego, low deserts, including the Coachella Valley and San Diego County deserts, could reach about 110°F and will be under an Extreme Heat Warning from 10 AM tomorrow through 8 PM next Monday.
The greatest heat risk is expected in the desert basins and parts of the Inland Empire and inland San Diego County, where even routine daytime activities can become hazardous without shade, rest and plenty of water.
How To Stay Cool
For those living inland or heading to desert communities, it is smart to push strenuous outdoor plans to early morning or evening, carry more water than you think you need and keep an eye on vulnerable neighbors and pets. Public cooling locations are available, with many libraries and recreation centers designated as Cool Zones, and 211 can help arrange transportation to those spots.

On The Commute
Morning fog may slow things down a bit near the waterfront and in low-lying valleys, but it should lift well before the evening rush. A light jacket will come in handy for the early drive, while the trip home, especially for inland commuters, is likely to feel warmer and drier as the new week gets underway.
