San Diego rolled out of bed under a solid gray ceiling today, as a stubborn deck of low clouds hugged the coast and kept things cool. Temperatures sat in the mid‑60s at San Diego International Airport, with a damp, chilly feel along the shoreline. Forecasters expect the gloom to break into partly sunny skies by mid‑ to late‑morning, with afternoon highs around 71°F and a cool night near 61°F.

Foggy Mornings, Sunny Afternoons

Overnight, the marine layer deepened to roughly 4,500 feet, shoving low clouds and a slight chance of patchy drizzle well inland before daybreak. Skies should gradually scatter through mid‑ to late‑morning, leaving most neighborhoods with a mix of sun and clouds. Along the coast, light to moderate southwest winds around 5–10 mph will keep daytime temperatures a bit below what you would normally expect for late June.

Afternoon Gusts Through The Passes

It is a different story in the higher terrain. Mountains, desert slopes and the usual wind‑prone passes will be breezier, with west‑to‑southwest surface gusts of roughly 20–35 knots (about 25–40+ mph) and local gusts up to 45 knots possible in favored canyon cuts. That can make exposed roads and bridges feel pretty blustery. The National Weather Service San Diego notes that these gusts could be locally strong but says no wind or marine advisories are in effect right now, though small craft operators should still use caution near the coast.

Plan For Commutes And Weekend Events

For the morning drive, coastal commuters should budget a little extra time for patchy low visibility and damp pavement, while inland routes will clear out earlier and warm into the upper 60s and low 70s by midday. Independence Day looks mild along the coast, with highs in the low‑ to mid‑70s on Saturday, and a gradual warming trend is expected to continue into next week.

Quick tips: bring a light jacket if you are heading to the coast this morning, secure outdoor furniture in canyon neighborhoods, and check conditions before boating or finalizing beach plans. Updates will follow if the National Weather Service issues any advisories through the holiday weekend.
