Over the past half-century, winter in Ukraine has ceased to be a stable season with predictable frosts and stable snow cover. Archival meteorological observations record a gradual but consistent change in temperature patterns. This is not about individual warm or cold winters, but about a long-term trend that has affected the duration of the cold season, the frequency of thaws, and the nature of weather anomalies. An analysis of average temperatures during the winter months allows us to trace how winter in Ukraine has changed from the mid-1970s to the present day.

The winters of the 1970s and 1980s as the temperature norm of the past
In the second half of the 20th century, winter in Ukraine remained relatively stable in terms of temperature. The average temperature during the winter months in the 1970s and 1980s fluctuated mainly within sub-zero values. Frosts below -10 degrees were common throughout most of the country, and long periods of steady snow cover shaped the classic image of Ukrainian winter. Thaws did occur, but they were sporadic and did not determine the overall temperature pattern for the season. It is this period that is often used as a baseline for comparing current climate change.
The beginning of the shift in the 1990s
In the 1990s, average winter temperatures in Ukraine began to show a gradual increase. Winters remained cold, but the number of days with severe frosts decreased. Periods with temperatures close to or above zero were recorded more and more often, especially in December and late February. It was at this time that meteorologists noticed a decrease in the duration of the continuous cold period, which previously covered almost the entire calendar winter.
The 2000s as a period of accelerated warming
Since the 2000s, changes in winter temperatures have become more noticeable. The average temperature during the winter months has risen by approximately one degree compared to the end of the 20th century. In some years, winter passed without sustained frosts in the central and southern regions of the country. Frequent thaws led to unstable snow cover or its complete absence. At the same time, short cold spells became more severe but less prolonged, changing the overall character of winter weather.

The 2010s and the new temperature reality
In the 2010s, the average winter temperature in Ukraine increasingly approached zero, and in some seasons exceeded it. Winters with positive average temperatures were no longer an exception. December in many regions began to resemble late autumn, while January and February were characterised by alternating short frosts and long periods of mild weather. Temperature anomalies became regular, confirming the formation of a new climatic regime for the cold season.
Winters of the early 2020s
The early 2020s cemented the trend towards warmer winters. Average temperatures during the winter months across the country were 2–3 degrees higher than in the 1970s and 1980s. Prolonged frosts became short-lived, and periods with above-zero temperatures covered a significant part of the season. Winter is increasingly losing its clear boundaries, blurring between late autumn and early spring.
What the 50-year trend shows
A comparison of average winter temperatures over the past 50 years shows a clear and consistent warming trend. The changes are uneven, with fluctuations from year to year, but the overall direction remains unchanged. Modern winters in Ukraine are significantly different from those remembered by previous generations. The temperature regime of the cold season has become more variable, milder and less predictable, which has long-term consequences for natural ecosystems, the economy and everyday life.
