Climate in Czechia
The Czech Republic has a temperate continental climate, with warm summers and cold, cloudy and snowy winters. The temperature difference between summer and winter is relatively high, due to the landlocked geographical position.
Within the Czech Republic, temperatures vary greatly, depending on the elevation. In general, at higher altitudes, the temperatures decrease and precipitation increases. The wettest area in the Czech Republic is found around Bílý Potok in Jizera Mountains and the driest region is the Louny District to the northwest of Prague. Another important factor is the distribution of the mountains; therefore, the climate is quite varied.
At the highest peak of Sněžka (1,603 m or 5,259 ft), the average temperature is only −0.4 °C (31 °F), whereas in the lowlands of the South Moravian Region, the average temperature is as high as 10 °C (50 °F). The country’s capital, Prague, has a similar average temperature, although this is influenced by urban factors.
The coldest month is usually January, followed by February and December. During these months, there is usually snow in the mountains and sometimes in the major cities and lowlands. During March, April and May, the temperature usually increases rapidly, especially during April, when the temperature and weather tends to vary widely during the day. Spring is also characterized by high water levels in the rivers, due to melting snow with occasional flooding.
The warmest month of the year is July, followed by August and June. On average, summer temperatures are about 20 °C (36 °F) – 30 °C (54 °F) higher than during winter. Summer is also characterized by rain and storms.
Autumn generally begins in September, which is still relatively warm and dry. During October, temperatures usually fall below 15 °C (59 °F) or 10 °C (50 °F) and deciduous trees begin to shed their leaves. By the end of November, temperatures usually range around the freezing point.
Most rain falls during the summer. Sporadic rainfall is relatively constant throughout the year (in Prague, the average number of days per month experiencing at least 0.1 mm of rain varies from 12 in September and October to 16 in November) but concentrated heavy rainfall (days with more than 10 mm per day) are more frequent in the months of May to August (average around two such days per month).
