Extreme heat wave shatters temperature records in Austria, threatens energy crisis across Central and Southern Europe

Aug 5, 2026

An extreme heat wave and severe drought are shattering records and triggering an energy crisis across Europe. Austria recorded an all-time high of 41.2°C on August 5, 2026, while dwindling water levels on the Danube and Sava rivers have forced nuclear plants in Hungary and Slovenia to curtail output. Wildfires have prompted evacuations in Albania, and agricultural sectors are reeling, with Britain facing its worst cereal harvest since 1984. Governments are urging widespread power and water conservation to prevent grid failures.

Austrian temperature records

▪Austria suffered its fourth-warmest July on record, with precipitation deficits reaching 90 percent at some measuring stations.
▪Austria recorded a temperature of 41.2 degrees Celsius in Bad Deutsch-Altenburg on August 5, 2026, breaking the previous record of 41.0 degrees Celsius set in Vienna on August 4, 2026.

Nuclear plant curtailments

▪Romanian naval forces conducted controlled explosions on the Danube's Bala canal to divert water flow toward the Cernavoda nuclear power plant.
▪Slovenia's Krsko nuclear power plant announced it would reduce reactor output to 80% of capacity due to high temperatures and low flows on the Sava River.
▪Dwindling water levels on the Danube River forced Hungary to largely shut down its sole nuclear plant, Paks, which relies on the river's waters for cooling.

Albanian wildfire evacuations

▪Emergency crews in Albania worked to contain a second wildfire, likely caused by lightning, south of the city of Gjirokaster.
▪Wildfires in Albania's southern Mallakaster region forced the evacuation of approximately 15 families along with their livestock and pets.

British cereal harvest decline

▪Britain's cereal harvest is projected to be the worst since comparable records began in 1984 due to an exceptionally dry and hot spring-summer period.
▪More than half of England and the entirety of Wales are officially in drought, following the driest July in 190 years.

Regional power conservation

▪Moldovan President Maia Sandu urged residents to conserve water and cut electricity use during evening peak hours as temperatures approached 38 degrees Celsius.
▪Hungarian companies and households reduced power consumption following a government appeal to ease pressure on the grid during the severe drought.
