I knew the temperatures here in Finland can be steady +5°C throughout the year¹ or then vary a lot². What I didn’t know is how large those fluctuations have been throughout the history. In January, which is statistically the coldest month of the year, the lowest temperature ever has been –51.5°C while the highest has been +10.9°C. In July, the statistically warmest month of the year, the lowest has been –5.0°C and the highest +37.2°C. All these measurement have been recorded at the official measurement stations (highs and lows at different stations, of course) of the Finnish Meteorological Institute. There could have even been higher and lower temperatures elsewhere.
