San Diego is waking up Sunday under mostly cloudy skies, with temperatures around 72 degrees near downtown and a humid feel in the air. The clouds should give way to a partly sunny afternoon topping out near 81, while a noticeably cooler pattern takes hold across the region from Tuesday onward.
Coastal Clouds Clear For A Mild Afternoon
Patchy low clouds and fog may linger along the coast through the early morning before scattering around 9 a.m. Sunday. West winds will run about 5 to 10 mph, and the chance of rain in the city is only 5%, according to the National Weather Service.
Monday should look similar, with partly sunny skies and a high near 81, followed by Tuesday's high around 80. Nights will remain mild, with lows near 69 or 70, so the coast may not get much overnight relief from the sticky conditions.
Heat Alerts Focus On Inland Areas
The National Weather Service has a Heat Advisory in effect until 8 p.m. Sunday for San Diego County valleys and mountains, while an Extreme Heat Warning covers the county deserts. Downtown San Diego's forecast is far cooler than the inland and desert zones, but residents heading east should be prepared for more intense heat.
People spending the day inland should drink plenty of water, limit strenuous activity during the hottest part of the afternoon and check on older adults, children and neighbors who may be more vulnerable to heat illness. The latest alert comes after San Diego's late-July hot spell, which was previously covered by Hoodline.
Cooler Weather Arrives By Midweek
Highs ease to about 79 Wednesday and 78 Thursday through Saturday, with a deeper marine layer likely to bring more morning and nighttime clouds and fog. The forecast also calls for afternoon and evening shower or thunderstorm chances in the mountains and deserts through Wednesday, with the best chances Monday and Tuesday.
High Tides Could Spill Into Beach Lots
Astronomical high tides are expected to exceed 7 feet Monday through Wednesday between about 8 and 9:30 p.m. Surf is forecast at only 2 to 3 feet, but the high tides could still cause minor overflow in low-lying coastal areas, including beach parking lots.
