An extended spell of hot, dry weather is setting up across Los Angeles County this week, bringing summer-like heat and elevated wildfire risks through Friday, May 23.
Daytime highs will climb into the 90s and even the low 100s away from the coast, with peak heat expected Wednesday and Thursday. Gusty sundowner winds will increase the risk of grass fires, especially in interior regions.

Monday Night:
Clear skies with mild overnight temps in the mid-60s. Winds calm after sunset.
Tuesday:
Hotter and drier. Interior areas may hit the mid-90s, with coastal spots remaining in the upper 70s. Gusty winds could begin developing by late afternoon.
Tuesday Night:
Clear and warm with lows in the 60s. Fire weather concerns increase.
Wednesday–Thursday:
The hottest days of the week. Inland highs soar into the upper 90s and lower 100s. Gusty sundowner winds heighten fire danger, particularly in foothill and canyon areas. Avoid outdoor burning and remain vigilant.
