Czech Republic's hottest day ever came unusually early

The Czech Republic hit 41.9°C on June 28, 2026, per its weather agency, beating the country's old July record of 40.2°C (1983) and August record of 40.4°C. In central Europe, the hottest days usually come in July or August — not June. Prague's Clementinum weather station, tracking temperatures since 1752, provides the long-term comparison.
