Apache Junction has a hot desert climate.
Long, extreme summers. Mild winters. Very little rain in any month — here's what that means in plain terms.
What this climate feels like
The four things a regular visitor actually wants to know:
Highs near 103°F in July. About 156 days a year above 90 °F.
Lows near 44°F in December. About 3 freezing nights a year.
About 10 in of rain a year. Wettest in January.
More sun than cloud through the year.
What "hot desert" means
Climate scientists sort every place on Earth into about 30 climate types, based on how hot, cold, wet and dry it is across the year. Apache Junction's type — hot desert — sits in the broad family of dry climates — deserts and steppes.
Researchers write climate types as a short letter code. Here is what each letter means:

Has Apache Junction's climate type changed?
A climate type is a coarse bucket. It can hold steady for years while the weather inside it shifts — or tip into the next bucket.
What this climate means for you
Xeriscape only — native succulents, cactus, desert-adapted shrubs. Vegetable gardens need shade cloth and heavy irrigation; many crops simply won't survive summer.
Travel in the cool half of the year (Nov–Mar). Summer travel is uncomfortable and outdoor activity is limited to dawn and dusk.
Brutal summer heat shapes daily life — early mornings and evenings are the practical outdoor windows. Air conditioning is near-universal; sun protection and hydration are constants.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from Apache Junction's measured 30-year climate normals (1991–2020) — the same official records behind Apache Junction's main climate page, so the two always agree.
Long-range climate maps measure things slightly differently and can place a city in a neighbouring category. Where they differ, this page uses the measured station record as the climate today.
