June was the fourth warmest in Czechia since records began

This June was one of the warmest in Czechia in the last six decades. At the same time, it was rich in precipitation, but there were large regional differences, with more rain in Bohemia while Moravia was slightly below average.

The average monthly air temperature reached 18.7 degrees Celsius last month, 2.2 degrees above the normal from 1991 to 2020, the Czech Hydrometeorological Institute (CHMÚ) said on their website. This is the fourth warmest June since 1961, which is as far back as the average temperature statistics extend.

"We assess June 2022 in the Czech Republic as strongly above normal in terms of temperature and above normal in terms of precipitation. The average length of sunshine this month was 206 hours, which is 122 percent of the normal for 1991 2020," CHMÚ stated.

Czechs experienced the warmest June so far since 1961 in 2019, when the average temperature was 20.7 degrees. Conversely, meteorologists recorded the lowest average temperature for June in 1985, which was only 13 degrees.

According to measurements made at Prague's Klementinum, where they have been monitoring the weather for almost two and a half centuries, June this year was exceptionally warm. In the historical tables kept since 1775, it ranks fifth. The average monthly temperature reached 22.3 degrees Celsius at the country’s oldest weather station.

In the territory of Bohemia, the average June air temperature reached 18.6 degrees, in Moravia and Silesia it was 0.3 degrees higher.

In Bohemia, 112 millimeters of rain fell in June, which was 37 percent above the long-term average, while Moravia and Silesia finished 5 percent below average with 79 millimeters.
