An early-autumn heat wave will keep temperatures in the San Diego area unseasonably high throughout the weekend.

Saturday’s forecast calls for a high of 85 degrees in much of coastal San Diego, with daily high temperatures remaining in the 80s through early next week. Highs inland will reach the mid 90s

“It will be another warm one out there this weekend, with fair skies and high temperatures running 7 to 14 degrees above seasonal averages,” the National Weather Service said.

The ocean will also be warmer, with water temperatures running more than 5 degrees above average.

On Friday afternoon temperatures under bright sunny skies topped out in the high 70s to mid-80s along the coast, low to mid-90s across the inland valleys, the low to high-80s in the mountains and as high as 106 in the deserts.

One back-country locale, Campo, tied its previous record Sept. 25 high of 100 degrees, last reached in 2001, the weather service reported.

The remainder of the weekend promises more of the same, with fair skies and temperatures running 7 to 14 degrees above seasonal averages, forecasters said. In a boon for surfers and ocean swimmers, local sea-water temperatures also will be on the warm side, averaging at least 5 degrees above normal for early fall.

The dry, summery conditions will continue through next week, meteorologists advised.
