Father's Day and Juneteenth brought pleasant but warming temperatures to San Diego County. The warming continues into this week, with summer-like conditions dominating all week long. The summer solstice actually takes place at 2:31 a.m. Tuesday, so the timing is spot-on.
Temperatures will hover a few degrees warmer than normal most of the week, with highs peaking in the second half of the week. By Wednesday, mid to upper 70s will be felt at the coast with upper 80s and even some 90s for inland valleys and mountains. Deserts jump up to the 113-115º range.
This past week officially marked the start of monsoon season, and the patterns reflect it. Monsoon flow impacts the four corners region, but could push toward San Diego County. There is the slightest chance for some thunderstorm activity for San Diego mountains and deserts for the second half of the week, peaking Wednesday. Actual impact in San Diego County looks minimal at this time.
