The climate in Czechia

Average daytime and nighttime temperatures


All climate diagrams on this page result from the collected data of 36 weather stations.
Weather stations at an altitude above 1450m have not been included.
All data correspond to the average monthly values of the last 20 years.


Back to overview: Czechia

Climate zone: Moderate zone of the northern hemisphere

The climate in Czechia is quite varied, but generally does not offer extreme climatic conditions. It is cold, wet and some nice summer months are also present. It rarely gets really warm here and you can safely leave your swimwear at home. The warmest and rainiest part of the country is South Moravian. The coldest is Moravskoslezský. Due to the warmer temperatures the best time for traveling is from May to September. Winter athletes will find their favorite weather conditions from December to February.

Temperature records of the last 73 years

The hottest temperature measured from 1949 to March 2022 was reported by the Praha Libus weather station. In August 2012 the record temperature of 39.6 °C was reported here. The hottest summer from July to September, based on all 12 weather stations in Czechia below 1450 metres altitude, was recorded in 1994 with an average temperature of 18.5 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 16.2 degrees Celsius. The average maximum daily temperature at that time was 24.7 °C.

The coldest day in these 73 years was reported by the weather station Ostrava Airp. Here the temperature dropped to -27.0 °C in January 2006. Ostrava Airp lies at an altitude of 260 meters above sea level. The coldest winter (January to March) was in 1963 with an average temperature of -5.0 °C. In Czechia, it is usual to have about 5.2 degrees more at 0.2 °C for this three-month period.

The most precipitation fell in May 2010. With 19.0 mm per day, the Lysa Hora weather station recorded the highest monthly average of the last 73 years. Incidentally, the region with the most rainfall for the whole year is around Lysa Hora. The driest region is near Brno Sokolnice.




Long-term development of temperatures from 1950 - 2021

In 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 1 measuring points in order to have actually comparable data over as long a period as possible.

In the years 1950 to 2021 there were only these 1 weather stations in the whole country, which reported continuous temperature values (Praha). 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 July 2006 with 22.1 °C. February 1956 was the coldest month with an average temperature of -11.7 °C.

The average annual temperature was about 8.3 °C in the years after 1950 and about 9.6 °C in the last years before 2021. So in less than 72 years it has increased by about 1.4 °C. This trend only applies to the selected 1 weather stations in Czechia. A considerably more comprehensive evaluation of the global warming has been provided separately.

Data basis and methodology

The data of the individual measuring stations are based on the archives of the German Weather Service, individual values averaged and supplemented by own elements. In order to determine a representative national average, average values were first calculated for each part of the country, which were then summarized at the national level. Thus, if a disproportionate number of weather stations are located in a small area, their number does not affect the national average. There are 12 stations in Czechia itself.In 24 cases, neighboring but nearby weather stations were also used to obtain more accurate values.
