Downtown Los Angeles will start Friday near 62 degrees before morning gray gives way to sunshine and an afternoon high near 82. Winds should remain light, setting up a mild day before warmer weekend temperatures.
Sunny Friday Leads Into A Warmer Saturday
The National Weather Service’s Los Angeles/Oxnard office forecasts mostly sunny skies Friday, with weak winds. The current outlook also puts Saturday’s high near 83 degrees, while the earlier outlook is available in this Hoodline forecast for comparison.
Saturday will begin with patchy fog before 11 a.m., followed by mostly sunny skies and a high near 83. Saturday night will turn mostly cloudy, with patchy fog returning after 11 p.m. and temperatures dropping to around 66.
Fog Returns Before A Brief Cooldown
How This Forecast Compares
According to the National Weather Service’s Los Angeles International Airport climate report, the Sept. 18 normal high is 76 degrees and the record is 92, putting Downtown LA’s forecast high near 82 above normal but well below the listed record. The recurring morning fog and later sunshine fit the forecast’s general marine-layer pattern.
For contrast, the Los Angeles County Department of Public Health reported an Extreme Heat Warning for the Los Angeles Inland Coast, including Downtown LA, from March 17 through March 20, 2026. The current forecast does not call for a comparable warning.
Sunday should reach about 82 degrees, with patchy morning fog giving way to partly sunny skies. Monday will be cooler, topping out near 78 after another foggy start.
The outlook includes possible precipitation for Sunday and Monday. No land-based weather warnings are listed, although separate marine advisories are in effect for some offshore waters, so boaters should check the latest coastal conditions before heading out.
