August is Los Angeles's hottest month, with the highest average daily high of the year. The month-by-month table above shows Los Angeles's exact average high and low for each month, based on the 1991–2020 climate normals — the standard 30-year reference period meteorologists use.

How much does it rain in Los Angeles?

Los Angeles's total annual precipitation and its wettest and driest months are shown in the rainfall-by-month section above.

Compare the average high, low, and precipitation for each month in the table above to pick the window that fits the weather you want.

Has Los Angeles gotten hotter?

There isn't enough data to say. The warming-stripes chart above plots Los Angeles's annual mean temperature for every complete year of station data from 1949 to 2025, but no trend line is fitted: the latest stretch of complete years with no gap over 10 years is 1999–2025, only 26 years (a trend needs at least 30). A shorter or broken record can't separate a climate trend from normal year-to-year swings.

Los Angeles's all-time record high — the hottest single day in the station record — is shown in the records section above, along with the date it occurred.

What is the record low temperature in Los Angeles?

Los Angeles's all-time record low and the date it was set appear in the records section above. Like the record high, it comes from the station's full daily history back to 1949, so it reflects the coldest day on record rather than an average winter low.
