California forecast: Heat wave to bring triple-digit temps across SoCal this weekend

Tips on staying cool during the heat wave

The weekend brings another round of dangerous heat. Here are some tips on staying safe.

LOS ANGELES - A brutal and dangerous heat wave that’s lingered in Southern California all week long will bring widespread triple-digit temperatures to several areas in the region from Orange to Ventura counties.

The National Weather Service (NWS) predicted the peak of the heat wave would hit by the middle of the week going into the weekend, and those flocking to beaches for some relief didn’t get much of that, with afternoon highs in the 90s or nearing the threshold along the coast. Santa Monica has a forecasted high of 91 degrees on Friday with Laguna Beach set to hit 88 degrees.

"The hottest days with this event are expected to be Friday and Saturday in most areas, and of those two days Friday has the slight edge of being the peak day," the NWS said. "Overnight night lows will be warming up as well, especially in the foothills and lower mountain locations where some areas may stay in the 90s much of the night. Not quite as hot overnight for the coast and valleys, but even there some warmer valley areas will stay above 80 until well into the overnight hours."

While it’s common for parts of California, such as the Inland Empire, valleys, and foothills to see temperatures above 100 degrees, other parts of the Southland are forecast to hit the triple-degree mark over the weekend.
