The winter of 2025-2026 has been reported as the second warmest winter in Greece since 1960, with meteorological data from meteo.gr highlighting unusually mild temperatures across the season. The warm conditions persisted, primarily in December 2025, January 2026, and February 2026, with an overwhelming 78 days (86% of the winter season) seeing temperatures above the average for the reference period of 1991-2020.

In stark contrast, only a few brief cold spells were recorded, where temperatures dipped below the average for a few days in early to mid-January 2026. The preliminary findings from forecast models reaffirmed last year's record of the warmest winter, which occurred in 2023-2024, emphasizing a worrying trend in climatic variations. The data suggests that recent winters are shifting significantly, marked by longer durations of higher-than-normal temperatures.

The trend of increasingly warmer winters is underscored by the fact that four out of the six warmest winters on record have occurred within the last six years, underscoring the pressing issues related to climate change. This pattern not only raises questions about ecological impacts and changes in seasonal weather behaviors but also indicates a necessity for broader discussions and actions regarding climate policy and environmental protections in Greece and beyond.
