San Diego is starting today under a classic May gray setup, with a blanket of low clouds, mild humidity and about 63°F at San Diego International (KSAN). The marine layer is clinging to the coast for now, but skies should brighten by late morning, leaving most neighborhoods with sunshine and highs near 74°F paired with a light southwest breeze.
Afternoon Sunshine and Light Breeze
By this afternoon, expect temperatures to top out around 74°F, with southwest winds generally 0–10 mph. Inland spots should feel comfortably warm, while the immediate shoreline hangs a bit cooler under the lingering shallow marine layer. Tonight, low clouds will creep back in, with mostly cloudy skies and a low near 61°F and some patchy drizzle redeveloping along the coast, according to the National Weather Service.
Foggy Mornings, Clear Afternoons
Early drivers along the coast and through the western valleys can expect low clouds and patchy fog to knock down visibility during the morning commute. Inland areas should peel back the cloud cover by mid- to late-morning, setting up another mostly sunny afternoon away from the beaches.
Week Ahead
The coming week looks steady and relatively quiet, with onshore flow keeping the daily routine familiar: clouds and fog at night and in the morning, clearing for daytime sun in most spots. A weak low sliding by to the north late in the week could trim temperatures by a few degrees, but no watches or warnings are expected across the county, and marine conditions are expected to remain non‑hazardous through at least Thursday.
