Summer's here. Stay hydrated and enjoy it. File photo.

Southern California sweltered under summer-like temperatures today, with one more day of the hot weather expected tomorrow before a cooling trend kicks in next week.

Saturday saw temperatures soar to 90 in Long Beach and even higher in parts of Los Angeles County, including 97 degrees in Pasadena and Chatsworth, 96 in Van Nuys and 94 in Burbank.

Downtown Los Angeles recorded a high of 86 degrees, according to the National Weather Service. In Orange County, it was 89 in Fullerton and 87 in Santa Ana.

High relative humidity and a lack of wind made conditions more uncomfortable.

Sunday’s highs were expected to once again reach the mid-80s downtown, and the 90s in parts of the San Fernando and Antelope valleys.

Forecasters said Monday should bring some relief, with highs in the upper 70s downtown and the upper 70s and 80s in the valleys.
