San Jose woke up today to clear skies and a cool start, with temperatures sitting in the mid‑50s at Mineta San José International Airport. Pockets of patchy fog are expected across low‑lying neighborhoods and the valley through the first half of the morning before sunshine returns. Afternoon highs should land in the low‑to‑mid 70s, with the rest of the week trending noticeably warmer.
Foggy Mornings, Sunny Afternoons
Widespread fog is expected to linger until about 10 AM, especially in low‑lying pockets and near creek corridors, while inland neighborhoods clear out first and coastal areas hang on to low clouds a bit longer. Once the marine layer burns off, afternoon sun will push temperatures into the low 70s across the valley, according to the National Weather Service.
How This Week Compares to Late February
Late February’s stormy stretch brought showers and small‑craft advisories across the Bay Area, but this week shifts to drier, warmer weather as high pressure builds back in. For more on that earlier wet spell, see the soggy surprise for commuters.
Afternoon Winds and Marine Advisories
Breezy conditions are expected along the coast and coastal mountains this afternoon, with northerly winds occasionally reaching strong to near‑gale force over the outer waters. The National Weather Service has posted Small Craft Advisories and a Gale Warning for portions of the coastal waters through Tuesday, and very rough seas are likely offshore. Boaters and anyone planning coastal activities should check local marine forecasts before heading out, especially this afternoon into Tuesday, per the National Weather Service.
What This Means for Your Commute and Plans
Allow extra time for early drives and use headlights in foggy stretches near low‑lying roads and creek crossings. By midday, sunny afternoons make for pleasant outdoor time, so bring sunscreen and a light layer for cool mornings and evenings. Expect a notable warm‑up by midweek, with highs climbing into the low 80s by Thursday and over the weekend.
