When is the best weather to visit Quartzsite?
Normal highs sit between 65°F and 85°F in January, February, March and November. Of those, November has the fewest days with rain (1).
That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

When is the last frost in Quartzsite?
In Quartzsite, the last spring frost (32°F) comes after January 28 in half of years and after February 24 in one year in ten; the first autumn frost comes before December 6 in half of years and before November 22 in one year in ten.

- First autumn frost, half of years before
- December 61 year in 10 before November 22; 9 in 10 before December 26
NOAA puts the median frost-free season at 315 days, and the season without a hard freeze (28°F) at 349 days.
A hard freeze (28°F) comes after January 7 in half of springs and before December 21 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts Quartzsite in zone 9a in ZIP code 85346, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, Quartzsite's NOAA station is in zone 9b: the coldest night of a typical year reaches 26°F (28 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.

Has Quartzsite been warmer than normal lately?
Over 33 complete years from 1960 to 2021, the station's annual mean temperature rose at a fitted 4.6°F per century (+0.25°C per decade). A fitted rate summarizes the whole record; single years swing well above and below it.

How does Quartzsite's climate compare?
Quartzsite is warmer than 88 of the other 96 places with their own NOAA record in Arizona, and wetter than 6. Across the 7,247 U.S. stations with normals, its annual mean of 73.7°F is warmer than 98%.

Which places near Quartzsite share this climate record?
2 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
