San Diego will begin Sunday under a cool blanket of coastal clouds, known locally as 'June Gloom', before the skies clear in the afternoon-according to forecasts from the National Weather Service. Morning temperatures will hover around 62°F while the afternoon high climbs to 74°F. Coastal regions are expected to remain mostly cloudy until midday -a characteristic feature of Southern California’s early summer weather.
Inland areas should see the cloud cover lift sooner, as rising air temperatures dissipate the low clouds. By early afternoon, most of the county will be enjoying partly to mostly sunny skies.
The NWS warned of gusty winds inland. Westerly mountain winds may reach 30–45 mph, with gusts up to 60 mph in passes.
