The climate in Czechia

Average daytime and nighttime temperatures


All climatic diagrams of this page are taken from the collected data from 56 measuring stations in Czechia.
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 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. Winter athletes will find their favorite weather conditions from December to February.

Temperature records of the last 71 years

The hottest temperature measured from 1949 to October 2020 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 71 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.


Long-term development of temperatures from 1950 - 2019

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 2019 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 2006 with 22.1 °C. 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 9.8 °C in the last years before 2019. So in less than 70 years it has increased by about 1.6 °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.
