San Diego woke up under a blanket of low clouds and mild air, with temperatures around 63°F at about 4:35 AM today. That gray start will not last long. The marine layer is expected to thin by late morning, letting the sun take over and push coastal highs into the mid-70s. Inland neighborhoods will warm up even more, setting the stage for a string of comfortable, mostly sunny afternoons across the metro area.
Afternoon Sun And Inland Warming
Highs are expected to reach around 75°F today, rise to about 78°F tomorrow, and peak near 80°F on Friday. Out in the lower deserts, temperatures could surge into the upper 90s and up to about 103°F by the weekend. Along the coast, northwest winds should stay on the lighter side, while inland areas may see gusts around 20-25 mph on Thursday and Friday. Desert slopes could see stronger gusts in the 30-40 mph range. At this point, there are no watches or warnings posted for San Diego County, according to the National Weather Service.
Foggy Mornings, Gusty Late-Day Breezes
A shallow marine layer, roughly 2,000 feet deep, will continue to feed low clouds and patchy fog into coastal neighborhoods and the western valleys overnight and into the early morning hours. That gray will burn off by late morning, flipping to sunny afternoons. Expect the fog to be most noticeable before dawn, especially for the early Friday and Saturday commute, while nighttime lows linger in the upper 50s to low 60s. For context, a similar short-lived warm pattern earlier this season followed a comparable setup.
What This Means For Your Plans
For now, this is a T-shirt by noon, a light jacket for dawn weather. Bring a layer for those foggy morning commutes, then plan to stash it once the sun breaks through. If you are outside around midday, sunscreen and plenty of water are smart moves. Inland spots will feel the warmup most from Friday into the weekend, so gardeners, pet owners, and anyone with outdoor chores may want to time the heaviest work for earlier or later in the day. Desert trips should factor in gusty winds and cooler nights, and boaters or early-morning beachgoers should be ready for pockets of reduced visibility near the coast.
