What is the coldest day ever recorded in Los Angeles?

Los Angeles's coldest day on record bottomed out at 22°F, set on January 12, 1949. Like the record high, it comes from the station's complete daily record, so it captures the most extreme cold the area has recorded rather than an average winter low.

The anomaly readout at the top of this page compares the current temperature against this month's normal high, so you can see exactly how unusual today is rather than guessing.

Los Angeles's record high of 118°F was set in 2020 (September 6, 2020), and its record low of 22°F in 1949 (January 12, 1949). Both are pulled from the station's complete daily record going back to 1949, so they reflect the true extremes rather than a recent or partial sample.

Yes — Los Angeles's annual mean temperature has trended about 9.1°F warmer since 1949, in line with the long-term warming seen across nearly every US city. That gradual shift in the average is separate from the all-time records above, which mark the single most extreme days rather than the trend, but a warming baseline is part of why recent years more often brush up against the record-high end.

Together the two extremes span 96°F — the full width of what this place’s weather has done across the station’s daily record back to 1949. Those edges are exactly why the anomaly readout at the top of this page is worth a glance: it shows where today falls between the normal and the record, so a hot afternoon can be judged against the real history rather than a hunch.
