About 0.8°F per decade, measured from Hrodna's official daily weather records, 1973–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Hrodna's warming is broadly in line with other cities across Europe — neither unusually fast nor unusually slow.
What has actually changed
Each card compares the 1970s (the first ten years of the
record) with recent years (the last ten) — the same span
the headline and the chart use.

Wetter on average
Hrodna's temperature, year by year
Average temperature for each year from 1973 to 2025.
a warmer-than-average year a cooler-than-average year
Each bar is one year. Most recent years sit above the older ones.
Some recent years still came in cool — warming is a slope,
not a straight climb.
When in the year the change shows up
How much warmer each month is now than in the 1970s.
Useful if you garden or care about a particular season —
otherwise the headline above already has the answer.
July has warmed the most — about 2.5°F. The warming runs across the whole year, not just one season.
Methodology & sources
Temperature — 1991–2020 normals computed from 30 years of daily observations at Bialystok, a weather station, about 78 km from the city centre. The underlying daily records come from NOAA's global station network.
