Cool-down and possible rain on the way for Big Bear ahead of Labor Day weekend

After nearly two weeks of temperatures in the 100s across the High Desert region, relief is finally on the way[1]. Big Bear, Wrightwood, and the surrounding mountain communities are expected to see highs hover in the high 60s and low 70s during the cooling period, according to the National Weather Service[1]. That's a welcome shift for year-round residents and Labor Day weekend visitors alike — though the holiday weekend may bring more than just cooler skies.

Weather experts are keeping a close eye on a potential tropical storm system that could push rain into Southern California over Labor Day weekend[1]. Down the hill, High Desert communities like Apple Valley, Hesperia, and Victorville can expect highs in the mid-to-low 80s starting Monday, September 1, before temperatures eventually climb back into the 90s[1].

The cool-down arrives roughly three weeks before fall officially begins. California's astronomical autumnal equinox falls on Tuesday, September 22, 2026[1].

How the potential rain event could affect fire conditions, mountain road safety, or holiday weekend operations at Big Bear Lake-area businesses and recreation areas could not be confirmed at press time. Residents and visitors planning trips to the valley over Labor Day weekend should monitor the National Weather Service forecast at weather.gov and check road conditions with Caltrans before heading up the hill.
