Long-term development of temperatures from 1954 - 2018
In the years 1954 to 2018 there were only 3 weather stations in the whole country, which reported continuous temperature values (Bialystok, Poznan, Warszawa Okecie). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was Juli 2006 with 22.8 °C. Januar 1987 was the coldest month with an average temperature of -12.3 °C.
The average annual temperature was about 7.2 °C in the years after 1954 and about 9.5 °C in the last years before 2018. So in less than 65 years it has increased by about 2.3 °C. This trend only applies to the selected 3 weather stations in Poland. A considerably more comprehensive evaluation of the global warming
has been provided separately.
