In 2025, the average temperature was higher than the 20-year average, with fewer ice days and more heat days, indicating a trend towards warmer conditions. Precipitation was above the 20-year average but not at historical extremes, suggesting a wetter year compared to recent averages.
In 2025, the average temperature was recorded at 11.8°C, which is higher than the average of 10.8°C over the past 20 years. The coldest day of the year was December 31st, with a temperature of -7.6°C, significantly warmer than the lowest temperature of -19.3°C recorded in the past 20 years and much warmer than the all-time low of -24.1°C in 1942. The hottest day was on August 13th, reaching 36.0°C, slightly below the highest temperature of 37.4°C recorded in the past 20 years and the all-time high of 39.0°C in 1952. There was only 1 ice day in 2025, which is considerably fewer than the average of 8.7 ice days over the past 20 years. In contrast, there were 23 heat days, surpassing the 20-year average of 16.6 heat days. These figures suggest a trend towards warmer conditions compared to both the past 20 years and historical records dating back to 1875. Table 1 provides a detailed view of these temperature values, while Table 2 lists the specific dates of these extreme conditions.
Precipitation in 2025 amounted to 929.7 mm, which is above the 20-year average of 795.5 mm but below the maximum of 1047.9 mm recorded in the same period. The year saw a maximum of 16 consecutive dry days and 11 consecutive wet days. The strongest 24-hour rainfall occurred on September 21st, with 45.2 mm, which is significant but does not reach the extremes of 94.8 mm recorded all-time in 1872. These precipitation patterns indicate a wetter year compared to the recent 20-year average, although not reaching historical extremes.
