Agua Caliente has a warm-summer Mediterranean climate.
Mild, rainy winters and hot, dry summers — here's what that means in plain terms.
What this climate feels like

Highs near 83°F in August. About 23 days a year above 90 °F.

More sun than cloud through the year.
What "warm-summer Mediterranean" 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. Agua Caliente's type — warm-summer mediterranean — sits in the broad family of mild, temperate climates.
Researchers write climate types as a short letter code. Here is what each letter means:

A warm-summer Mediterranean climate (Csb) — these recognizable cities share it. If you know one of them, you know roughly what to expect.
Has Agua Caliente's climate type changed?
Stable — Agua Caliente's climate has held the same type between the 1971–2000 and 1991–2020 normals. The label is steady; the climate beneath it is still warming.
What this climate means for you
Cool-season vegetables, stone fruit, berries and hops excel. Wine grapes do well at the warmer end.
Late spring through early autumn is the pristine window — warm, dry, sunny. Winter is wet but never brutal.
Comfortable year-round — sunny, dry summers and mild, wet winters. Heating is modest; AC is rarely necessary.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from Agua Caliente's measured 30-year climate normals (1991–2020) — the same official records behind Agua Caliente'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.
