The climate in PolandAverage daytime and nighttime temperatures
All climatic diagrams of this page are taken from the collected data from 63 measuring stations in Poland.
Weather stations at an altitude above 700m have not been included.
All data correspond to the average monthly values of the last 20 years.

The climate in Poland widely corresponds to the German weather conditions. It is cold, wet and a few beautiful summer months are also happening. It rarely gets really warm here and you can safely leave your swimwear at home. Due to the warmer temperatures the best time for traveling is from May to September. Nearly unattractive for tourists are the cold months from November to March.

Temperature records of the last 69 yearsThe hottest temperature measured from 1951 to October 2020 was reported by the Warszawa Okecie weather station. In August 2013 the record temperature of 37.0 °C was reported here. The hottest summer from July to September, based on all 25 weather stations in Poland below 700 metres altitude, was recorded in 2018 with an average temperature of 18.7 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 16.4 degrees Celsius. The average maximum daily temperature at that time was 24.3 °C.
The coldest day in these 69 years was reported by the weather station Warszawa Okecie. Here the temperature dropped to -23.4 °C in January 2010. Warszawa Okecie lies at an altitude of 107 meters above sea level. The coldest winter (January to March) was in 1963 with an average temperature of -6.3 °C. In Poland, it is usual to have about 5.9 degrees more at -0.4 °C for this three-month period.
Long-term development of temperatures from 1954 - 2019In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 3 measuring points in order to have actually comparable data over as long a period as possible.
In the years 1954 to 2019 there were only these 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 2006 with 22.8 °C. 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 9.7 °C in the last years before 2019. So in less than 66 years it has increased by about 2.5 °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.
