LOS ANGELES, CA – A shimmer of early light over the basin this Monday signals a shift toward unseasonable heat, with the Santa Monica Mountains already warming before sunrise. A Heat Advisory takes effect Tuesday morning for Los Angeles and Ventura counties, marking one of the hottest late-October spells on record for the region.
According to the National Weather Service in Oxnard, temperatures are expected to climb into the low to mid-90s across interior Los Angeles, Woodland Hills, and Burbank by Tuesday afternoon, with coastal zones in the mid-80s. The advisory runs from 10 a.m. Tuesday through 7 p.m. Wednesday, when the hottest, driest air will sweep through inland valleys and foothills. Winds may briefly gust from the northeast, elevating brush fire concerns in dry canyons and near Highway 101.
Public health officials warn that heat illness can strike quickly, especially for children, older adults, or those without air conditioning. Residents are urged to stay hydrated, limit outdoor work between 10 a.m. and 4 p.m., and check on neighbors who may be vulnerable. Air-conditioned community centers will remain open across Los Angeles County for cooling relief.
Wednesday stays hot, with highs near 92 before gradual cooling arrives Thursday. Coastal breezes will strengthen by Friday, bringing a more seasonable pattern just in time for Halloween. Trick-or-treaters can expect mild evening air—ideal for costumes and outdoor events—but the weekend ahead signals change. Cooler Pacific air builds in by Saturday, a subtle reminder that despite this week’s heat, a chilly November lies just ahead.
