San Diego is starting today beneath mostly cloudy skies, with temperatures around 72 degrees at the coast and a mild afternoon ahead. The city should reach about 76 degrees, with little chance of rain, before dipping to roughly 68 overnight.

Some afternoon brightness may break through, but low clouds are expected to linger near the beaches and nearby coastal neighborhoods. Southwesterly winds should stay light at 5 to 10 mph, and the current forecast lists no watches, warnings or advisories, according to the National Weather Service San Diego.

Clouds Hang On Near The Coast

The cloud deck could stick around through much of the afternoon at the shoreline and as far as about 10 miles inland, while some inland neighborhoods see more sun. Tonight remains mostly cloudy, with west winds of 0 to 5 mph and a low near 68 degrees.

Tomorrow brings a small step toward brighter weather, with partly sunny skies and a high near 77 degrees. Overnight temperatures should fall to around 67, keeping the coast comfortable even if the morning starts gray.

Weekend Warmup Stays Manageable

Saturday reaches about 78 degrees under partly sunny skies, with northwest winds of 5 to 10 mph and gusts up to 20 mph. Next Sunday turns mostly sunny with a high near 79, followed by highs around 80 next Monday and 81 next Tuesday.

The broader weather pattern is shifting toward drier air after today's cooldown, setting up a slow warmup into early next week. San Diego's coastal neighborhoods should remain mild, but inland valleys and the lower deserts will be much hotter, with desert temperatures near 100 degrees today and potentially reaching 106 to 110 by next Tuesday.
