San Diego woke up to a classic marine layer today, with a blanket of low, gray clouds and cool, damp air setting the tone early, before the sun muscles through for a brighter afternoon. Coastal neighborhoods are set to top out in the low 70s, with inland spots running a bit warmer. A light west-to-northwest breeze will keep the bayfront feeling comfortable rather than cold.
According to the National Weather Service San Diego, today's high should land near 72°F, with an overnight low around 62°F and winds generally in the 0 to 10 mph range. There are no watches or warnings in effect for San Diego County at this time.
Foggy Mornings, Clearer Afternoons
Thick low clouds will hug the coast through the morning and push into nearby valleys before gradually breaking up by early afternoon. Hour-by-hour forecasts show temperatures climbing from the mid-60s near the shoreline into the low-70s later in the day, as a modest sea breeze builds into mid-afternoon.
If you are heading out early, plan for layers for the cool start, then peel them off as the sun comes out. After sunset, a lighter jacket will come in handy once the onshore flow brings that chill back in.
Weekend And Holiday Outlook
Saturday, July 4, is shaping up as partly sunny with a high near 74°F along the bay and beaches, a sweet spot for holiday events. Inland neighborhoods will run noticeably warmer, and that inland heat will keep inching up as the slow warming trend continues into next week.
By midweek, coastal highs are expected to reach the mid-70s, while inland areas are expected to push toward the 90s. Down in the lower deserts, highs could reach around 110-114°F, bringing a moderate to locally major heat risk. If you have outdoor plans later in the week, it is worth checking updated forecasts so the heat does not sneak up on you.
Heat And Safety
Anyone heading inland or out to the deserts next week should plan around the hotter afternoons. Bring plenty of water, take breaks in the shade when you can and try to avoid heavy exertion during the midday peak.
San Diego County runs a network of free, air-conditioned "Cool Zones" where residents can escape the worst of the heat during hotter spells. Locations and hours can change, so it is smart to confirm details before you go. A full list is available at San Diego County Cool Zones.
