Grants Pass has a hot-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 91°F in July. About 53 days a year above 90 °F.
Lows near 35°F in December. About 56 freezing nights a year.

A roughly even mix of sun and cloud.
What "hot-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. Grants Pass's type — hot-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:

Has Grants Pass'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
Wine grapes, olives, citrus, figs and rosemary thrive. Summer-active gardens need drip irrigation; cool-season crops do well over winter.
Spring and autumn are the perfect window — warm, dry and clear without summer's heat. Summer is hot but rain-free.
Sunny summers, mild winters and an outdoor lifestyle. Wildfires are the dominant summer risk in many areas.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from Grants Pass's measured 30-year climate normals (1991–2020) — the same official records behind Grants Pass'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.
