European heatwave breaks temperature records in Czech Republic and Denmark

A severe heatwave is sweeping Europe, setting new national temperature records. In the Czech Republic, the town of Doksy recorded a historic 40.6 °C, surpassing the previous 40.4 °C set in 2012. The Czech meteorological institute issued the highest heat alert and warned of dangerous conditions, including “tropical nights” where temperatures stay above 20 °C.

Denmark also logged its hottest June day, with 36.6 °C measured north of Odense, the highest temperature since the country's records began in 1874. The Danish weather service confirmed the unprecedented heat.

The extreme temperatures extend across the Balkans, where red alerts have been issued and forecasts predict up to 39 °C in Serbia, North Macedonia, Bosnia‑Herzegovina and Montenegro. European health authorities estimate that at least 193 million people will face temperatures above 35 °C today, including around 75 million in Germany. Authorities have introduced measures such as bans on open fires in Prague and advise vulnerable groups to stay hydrated and avoid prolonged sun exposure.
