Los Angeles is in for a dramatic weather shift this week as unseasonably high temperatures push into the region before a significant cooldown arrives just in time for the weekend. The city will see summer-like heat midweek, with highs soaring to 85°F (29°C) on Thursday, but don’t get too comfortable—the warmth won’t last. By Friday, cooler air moves in, bringing temperatures down nearly 20 degrees, with a slight chance of rain by Sunday.
Why Is Los Angeles Heating Up So Suddenly?
A strong high-pressure system is building over California, acting like a heat dome that traps warm air over the region. This system will push temperatures well above the seasonal average, making it feel more like early summer than late winter. The heat will be most intense on Wednesday and Thursday when daytime highs reach the mid-80s in some areas.
While this warmth is perfect for beachgoers and outdoor enthusiasts, it comes with some risks. The National Weather Service has issued a minor heat risk warning, advising those sensitive to heat—such as the elderly, children, and people with underlying health conditions—to take precautions. The agency also warns of dangerous surf conditions, with waves reaching up to 18 feet along some beaches.
By Friday, the high-pressure system will weaken, allowing cooler Pacific air to filter in. This shift will cause temperatures to drop quickly, bringing daytime highs back down to the upper 60s by the weekend. Along with the cooler air, more clouds will roll in, and there’s even a slight chance of rain by Sunday.

What This Means for LA Residents and Visitors
For those enjoying outdoor activities, the next few days will feel like summer in the middle of winter. Whether you’re heading to the beach, going for a hike, or dining outdoors, the weather will be ideal. However, with the UV index climbing, it’s important to use sunscreen, wear light clothing, and stay hydrated.
Beachgoers should be particularly cautious. While the warm temperatures may make the ocean seem inviting, the beach hazards statement warns that waves could reach up to 18 feet in some locations, creating dangerous conditions for swimmers and surfers.
By the weekend, the weather will take a sharp turn. A cooldown of nearly 20 degrees will remind Angelenos that winter isn’t quite over yet. If you’ve been enjoying the heat, make the most of it while you can because by Friday, a chilly breeze and overcast skies will replace the sunny, summer-like conditions.
Looking Ahead: Is More Heat on the Way?
After this weekend’s cooldown, early March is expected to bring more typical Los Angeles weather, with highs in the mid-60s to low 70s. While no major storms are expected, another warm-up isn’t out of the question later in the month. Meteorologists recommend staying updated on the forecast, as rapid temperature swings are common in Southern California during seasonal transitions.
For now, enjoy the sunshine, but be prepared for a dramatic shift as the week comes to a close!
