Kostyantynivka's weather extremes

The hottest, coldest, wettest and snowiest days Kostyantynivka 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 Artemivsk station 22 km away. Updated through February 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 Kostyantynivka has recorded — each shown against what a normal day that time of year looks like.

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.

Kostyantynivka's record heat sits well above even a hot day for the season — July's 103°F is about 18°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, Kostyantynivka's warmest days reach the mid-80s°F and its coldest nights drop to the mid-10s°F. But across the record it has gone as high as 103°F and as low as −30°F. A single day has delivered over 4 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 — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.

Precipitation — 1991–2020 normals computed from 2 years of daily observations at Donetsk, a weather station, about 51 km from the city centre. The underlying daily records come from NOAA's global station network.
