Moscow's weather extremes

The hottest, coldest, wettest and snowiest days Moscow has recorded — the outer limits of what its weather can do. This station's daily record ended in 2022, so these are historical extremes from that period, not records updated to today.

Based on 50+ years of daily weather observations (1971–2022), from the Moscow station 9 km away. Updated through January 2022 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

The four kinds of extreme

The hottest, coldest, wettest and snowiest single days Moscow has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
101°F Jul 29, 2010

That is about 24°F hotter than a normal July afternoon in Moscow (typical high near 77°F).

The three most extreme on record

❄️ Coldest night
-36°F Dec 31, 1978

About 56°F colder than a normal December night in Moscow (typical low near 20°F).

3 -27°F Jan 1, 1979
🌧️ Most rain in one day
3.46 in Aug 15, 2016

More rain in a single day than Moscow usually gets in the whole month of August (typical August total about 3.2 in).

How hot and cold it gets, month by month

The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.

Moscow's record heat sits well above even a hot day for the season — July's 101°F is about 24°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.

In plain terms

In a normal year, Moscow's warmest days reach the high 70s°F and its coldest nights drop to the mid-10s°F. But across the record it has gone as high as 101°F and as low as −36°F. A single day has delivered over 3 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
Methodology & sources

Temperature & precipitation — 1991–2020 normals computed from 29 years of daily observations at Moscow, a weather station, about 9 km from the city centre. The underlying daily records come from NOAA's global station network.
