Effect of climate change

Today's climate (1996–2025) compared with 1961–1990:

In short

Temperature ≈ °C no clear change
Rain mm ≈ rain days ≈ there were 37 rain days a year in 1961–1990

Year by year

Temperature of each year

−2.4 °C+2.4 °C

Against 1961–1990 the mean temperature of today (1996–2025) has changed by +0.2 °C; in the last ten years by +0.3 °C. Warmest year: 1961 (+0.9 °C), coldest: 1992 (−1.2 °C).

September and January warmed the most (+0.8 and +0.5 °C), November the least (0.0 °C). The warm season (above the annual mean of then, 19 °C) begins 3 days earlier and ends 2 days later.
