Temperatures slowly warm before weekend heat wave hits San Diego

SAN DIEGO (KUSI) — Gray skies hang over San Diego Wednesday morning, but after the marine layer breaks apart mid-day expect sun and average temperatures before a heat wave hits San Diego over the weekend.

A ridge of high pressure starting to build over San Diego will start to break apart that marine layer earlier in the day, allowing sun to shine and temperatures to slowly climb leading into the weekend.

The National Weather Service issued a beach hazards statement warning Tuesday of rip and longshore currents. It is set to remain in effect through Thursday evening.  Beaches may see surf of 4 to 6 feet with some sets reaching 7 feet.

This weekend a heat wave will hit San Diego. Temperatures are expected to climb up to 20 degrees above average in some areas.

The NWS has issued an excessive heat watch for inland areas that goes into effect Sunday morning to Tuesday evening.

Daily high temperatures over the weekend are predicted to be in the upper 80s to low 90s at the beaches, in the 90s in the mountains, 100 to 110 degrees in the valleys and high desert, and more than 115 degrees in the low deserts.
