Hungary endures record-breaking August 2026 heatwave

record temperatures water shortage railway speed limits forest fires low Danube water

Hungary faced an extreme heatwave in early August 2026, with record temperatures recorded across the capital and surrounding areas. The highest temperature reached 41.6 °C in Újpest and 41.4 °C in Budakalász, breaking previous national records. The national health authority lowered the heat‑alert level from third‑ to second‑degree on 8 August, keeping it in force until 11 August.

The prolonged high temperatures strained water supplies. A water shortage affected about 2,300 residents in Tápiószelén, and voluntary water consumption fell by roughly 9 % nationwide. Low Danube water levels limited the Paks Nuclear Power Plant to about 230 MW (≈10 % of capacity). The railway operator MÁV imposed speed limits on 19 lines and applied a white, heat‑reflective coating to rails to prevent track deformation. Forest and vegetation fires burned roughly 150‑200 ha, and the military deployed helicopters to assist firefighting.

Authorities urged the public to stay hydrated, avoid outdoor activity during peak heat, and use shade. Temporary measures such as home‑office extensions and energy‑saving steps by companies were also announced to reduce electricity demand.
