Los Angeles in December

Among the months with the most rainy days, and nights turn chilly. On clear days the air is crisp and the skyline sharp. The Christmas season keeps flights and rooms pricey. On dry-wind days, keep an eye on wildfire news.

December was mild: 19°C by day, 10°C at night, the kind of range where you stop checking the thermometer. Out of 31 days, about 5 brought rain; the rest stayed dry. 2 of 20 years had a completely dry December, while 2010 reached 12 rain days.

Days were short. Daylight shrank from 10.1 to 9.9 hours across the month, so plan outdoor sights early. The warmest year was 2017, with highs averaging 23.4°C, 4.2°C above normal. Cold snaps happened: the record low for December was 2.9°C, set in 2010.
