Heat Wave Hits SoCal, Coastal Areas Only Reprieve According to NWS

A mini-heat wave is coming to Southern California; high temperatures inland, coastal areas of Orange County at the mercy of the marine layer

SEAL BEACH, CA—Mild weather will give way to a mini-heat wave beginning today, with forecasters predicting temperatures well above normal by week's end. If you are searching for beaches, might want to look further south than Seal Beach, where partial ocean swimming closures are still in effect, thanks to the raw sewage spill from Long Beach, Calif.

High pressure is expected to settle over the area beginning today, lessening the marine layer and ushering in warmer weather.

"By Friday, highs in the 95 to 105 range will be common away from the coast, with coastal areas at the mercy of the ebbs and flows of the marine layer,'' according to the National Weather Service. "Overnight low temperatures will also be on the rise, with above-normal lows by Friday morning and a few 70s popping in.''
