Hungary sets new all-time temperature record as heat wave rewrites national and Budapest records
Hungary recorded its highest temperature since observations began on June 30, 2026, when the temperature reached 42°C (107.6°F) in Szécsény, surpassing the previous national record of 41.9°C (107.4°F) measured in Kiskunhalas in 2007. The same heat wave also established a new all-time temperature record in Budapest and rewrote numerous national and capital daily maximum and minimum temperature records between June 29 and July 1, according to HungaroMet.

Hungary recorded its highest temperature since observations began on June 30, 2026, when the temperature reached 42°C (107.6°F) in Szécsény, surpassing the previous national record of 41.9°C (107.4°F) measured in Kiskunhalas on July 20, 2007.
According to HungaroMet, the measurement also established a new national daily maximum temperature record for June 30, replacing the previous record of 39.6°C (103.3°F) measured in Berettyóújfalu in 2022.
The capital also established a new all-time temperature record during the same event. HungaroMet measured 41°C (105.8°F) at its Budapest Lágymányos station, exceeding Budapest’s previous absolute record of 40.7°C (105.3°F) set at Budapest Pestszentlőrinc on July 20, 2007. The measurement also broke Budapest’s June 30 daily maximum temperature record, replacing 38.2°C (100.8°F) measured at Budapest Újpest in 2022.
The heat wave had already begun rewriting temperature records the previous day. On June 29, the temperature reached 41.8°C (107.2°F) in Aszód, establishing a new national daily maximum temperature record for the date and exceeding the previous June 29 record of 38.4°C (101.1°F) measured in Dévaványa in 2022.
Budapest also established a new June 29 daily maximum when Újpest reached 40.3°C (104.5°F), surpassing the previous record of 37.5°C (99.5°F) measured at Budapest Budatétény in 1947.
The unusually persistent heat also produced exceptionally warm nights. During the night of June 29, the temperature fell to only 27.1°C (80.8°F) at Budapest János-hegy and Dobogókő, establishing new national and Budapest daily minimum temperature records for the date. The previous national record was 24.8°C (76.6°F), measured at Keszthely-Tanyakereszt in 2022, while Budapest’s previous record was 23.2°C (73.8°F), measured at Lágymányos the same year.
Additional overnight records followed after the heat wave reached its peak. At dawn on June 30, the temperature dropped only to 26.9°C (80.4°F) in Siófok, setting a new national daily minimum temperature record and replacing the previous 24.7°C (76.5°F) measured at Budapest Lágymányos in 2022. In the capital, Budapest János-hegy recorded a daily minimum of 26.6°C (79.9°F), breaking the previous June 30 record of 24.7°C (76.5°F).
Another exceptionally warm night followed. By dawn on July 1, the temperature at Budapest Lágymányos had fallen only to 26.8°C (80.2°F), establishing new national and Budapest daily minimum temperature records for July 1. The previous national record was 26°C (78.8°F), measured in Pannonhalma in 1950, while Budapest’s previous July 1 record of 24.4°C (75.9°F) had also been measured at Lágymányos in 2022.
The succession of records reflected the peak of an intense European heat wave that affected Hungary over several days, with daytime temperatures exceeding 40°C (104°F) across parts of the country and exceptionally warm nights limiting overnight cooling. HungaroMet noted that the reported values remain subject to its standard verification procedures for historical temperature extremes.
