Mammoth Lakes 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
The four things a regular visitor actually wants to know:
Highs near 26°C in July.
Lows near −8°C in February. About 182 freezing nights a year.
About 553 mm of rain a year, plus 448 cm of snow. Snow falls through the winter months.
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. Mammoth Lakes'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:
Cities with the same climate as Mammoth Lakes
A warm-summer Mediterranean climate (Csb) — these recognizable cities share it. If you know one of them, you know roughly what to expect.
Mammoth Lakes sits near a climate boundary
This city sits right on the line between warm-summer mediterranean and the next type along. Different climate maps file it on different sides of that line; the lived weather doesn't change at the line — it's a naming boundary, not a wall.
Has Mammoth Lakes's climate type changed?
Stable — Mammoth Lakes'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 Mammoth Lakes's measured 30-year climate normals (1991–2020) — the same official records behind Mammoth Lakes'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.
Methodology & sources
Temperature & precipitation — 1991–2020 normals computed from 24 years of daily observations at Mammoth Lakes RS, a weather station, inside the city. The underlying daily records come from NOAA's global station network.
