Czechia sees first summer day early, Sunday’s temperatures may reach 30°C

The Czech Republic recorded its first summer day of the year on Saturday with temperatures crossing the 25 degrees Celsius mark. Temperatures on Sunday could climb to as high as 30 degrees Celsius, especially in the Polabí region, the Czech Hydrometeorological Office reported.

If that threshold is reached, it would rank among the earliest tropical days ever recorded in the country.

Data from 1961 to 2025 show that the first tropical day usually occurs around the 145th day of the year, i.e. in late May.
