June Gloom Lingers This Weekend as High Pressure Poised to Deliver Midweek Inland Heat
A building western high will compress the coastal marine layer and push inland highs into the upper 80s and 90s next week.
Overview
- Thick marine layer continues this weekend with low clouds, patchy drizzle and cool coastal highs that leave Central Coast and San Diego beaches noticeably below normal.
- A Beach Hazard Statement remains in effect for the entire San Diego coast through Sunday evening for elevated surf up to 6 feet and strong rip currents that endanger swimmers.
- Gusty westerly winds of 25 to 45 mph are expected through mountain passes and desert areas this weekend, raising risks of blowing dust, reduced visibility and localized fire-weather concerns.
- Forecast models show the pattern changing starting Monday and peaking Wednesday when the upper-level high compresses the marine layer and inland valleys could reach the upper 80s to mid 90s.
- The marine layer’s compression will keep immediate coast cooler while exposing inland communities to heat risks and higher overnight temperatures, and forecasters note a small (about 20%) chance of a brief Central Coast shower or thunderstorm midweek.
