Ville-Marie has a warm-summer humid continental climate.
Warm summers and long, cold winters with snow. Rain in every 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 26°C in July.
Lows near −14°C in January.
About 1029 mm of rain a year, plus 213 cm of snow. Snow falls through the winter months.
Cloudy skies much of the year.
What "warm-summer humid continental" 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. Ville-Marie's type — warm-summer humid continental — sits in the broad family of four-season continental climates.
Researchers write climate types as a short letter code. Here is what each letter means:
Cities with the same climate as Ville-Marie
A warm-summer humid continental climate (Dfb) — these recognizable cities share it. If you know one of them, you know roughly what to expect.
Ville-Marie sits near a climate boundary
This city sits right on the line between warm-summer humid continental 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 Ville-Marie's climate type changed?
Stable — Ville-Marie'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
A ~5-month growing season — hardy apples, maples, root vegetables, brassicas. Heat-loving crops are marginal without season-extension.
Summer is the practical window; autumn brings spectacular foliage in many areas. Winter is for skiing and ice — beautiful but brutal.
Long, cold winters and warm but not hot summers. Heating dominates. A strong outdoor culture in summer to balance the long indoor winter.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from Ville-Marie's measured 30-year climate normals (1991–2020) — the same official records behind Ville-Marie'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 22 years of daily observations at Montreal/pierre Elliott Trudeau Intl A, a weather station, about 14 km from the city centre. The underlying daily records come from NOAA's global station network.
