Downtown Los Angeles is starting Thursday, August 6, 2026, near 66°F with humidity close to 90%, but the mild morning will not last. Sunny skies will push temperatures rapidly upward, with a high near 85°F expected by the afternoon. An early northwest breeze around 12 mph, with gusts near 16 mph, should give way to lighter southwesterly winds later in the day.
Sunny, Hotter By Lunch
Temperatures are expected to reach the low 70s by midmorning, approach 80°F before noon and hit about 83°F at lunchtime. The warmest stretch should run from roughly 1 to 3 p.m., when readings are expected to top out near 85°F. Rain is highly unlikely, with the forecast putting the chance at just 1% to 2%.
Sticky Nights And A Hot Weekend
Thursday night will turn partly cloudy with a low near 67°F, and the overnight air may feel warmer and more humid than usual. Friday and Saturday are forecast to reach 88°F, followed by a Sunday high near 89°F, while nighttime lows remain in the upper 60s. The National Weather Service says coastal areas and lower coastal valleys could see overnight and morning low clouds or fog before afternoon clearing.
Cooling Arrives Next Week
A modest cooldown is expected to begin Monday, when Downtown Los Angeles should reach about 87°F. Highs are forecast near 86°F Tuesday and 84°F Wednesday as stronger onshore flow and a deeper marine layer bring more relief, although humid nights may linger.
Heat Risk Is Highest Inland
The most serious heat alerts are focused on lower mountain elevations and far-inland areas, with an Extreme Heat Warning and Heat Advisory in effect across portions of the region through 8 p.m. Sunday. Even neighborhoods outside those alert zones should limit strenuous activity during the hottest afternoon hours, drink water and avoid leaving children or pets in parked cars. Gustier afternoon winds, hot conditions and dry vegetation could also raise fire-weather concerns farther inland, according to the National Weather Service.
