Saturday, March 28, 2026: San Diego woke to patchy fog draped over the coastal mesas and western valleys early this morning, although those low clouds are expected to scatter for most spots by mid-morning. By afternoon, most neighborhoods should be basking in mostly sunny skies and another round of unusually warm temperatures, with inland areas heating up the most.
Afternoon Winds Pick Up
According to the National Weather Service San Diego, patchy fog will give way to mostly sunny skies, with highs near 80°F inland and in the mid 70s at the coast. Northwest winds are forecast at 5 to 15 mph, with gusts up to 25 mph in more exposed spots late this afternoon into early evening, so it is a good idea to secure lightweight outdoor items before they start rattling around.
Foggy Mornings, Sunny Afternoons
Drivers should expect reduced visibility for the morning commute where the fog lingers, especially on coastal mesas and in western valleys. Conditions should improve by mid-morning once the marine layer starts to break up. After that, temperatures jump quickly, so bringing a light layer is smart if you plan to bounce between cooler beaches and warmer inland neighborhoods.
Weekend Outlook
Highs will stay well above average through Sunday, with inland temperatures near 81°F and overnight lows holding in the upper 50s to low 60s. This run of warm days follows the mid March stretch that nudged some records earlier in the month, as covered in mid March heat wave nears records.
Midweek Change
By midweek, a shallow trough may bring cooler, breezier conditions and a deeper nighttime marine layer, although precipitation chances remain low. If you have outdoor plans later in the week, expect afternoon temperatures to ease back toward seasonal averages by Wednesday and Thursday.
Practical tips for the next couple of days: allow extra time during foggy morning commutes, keep water handy during the warm afternoon hours, and secure loose outdoor furniture before gustier periods set in. No watches or warnings are in effect for San Diego County this weekend based on current local forecasts.
