How extreme does Twentynine Palms's weather get?

The hottest, coldest, wettest and snowiest days Twentynine Palms has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 50+ years of daily weather observations (1971–present), from the Twentynine Palms station 2 km away. Updated through May 2026 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

Twentynine Palms's record heat sits well above even a hot day for the season — July's 118°F is about 14°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.

In plain terms

In a normal year, Twentynine Palms's warmest days reach the mid-100s°F and its coldest nights drop to the low 40s°F. But across the record it has gone as high as 118°F and as low as 10°F. A single day has delivered over 3 inches of rain or close to 6 inches of snow. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
