Balkans Face Record Heat Wave with Red Alerts and Health Warnings
A severe heat wave is sweeping the Balkans, with temperatures reaching up to 48 °C in parts of Serbia and 42 °C in Mostar, Bosnia‑Herzegovina. National meteorological services in Croatia, Bosnia‑Herzegovina, Serbia and Montenegro have issued red or orange weather alarms, warning of very high heat and the risk of dehydration, heat‑stroke and cardiovascular events. Health agencies across the region advise avoiding direct sun between 11:00 and 17:00, staying well‑hydrated, wearing light clothing and limiting strenuous outdoor work. Employers are urged to protect outdoor workers by adjusting schedules, providing breaks and cooling measures.
Serbian President Aleksandar Vučić warned that the Danube’s water level is at a critically low point, threatening further drops that could affect water‑intake facilities and hydro‑electric power. Traffic congestion has intensified on major routes to the Adriatic, with long queues reported on highways in Bosnia and Croatia.
Local authorities have responded with public‑cooling measures: the city of Zagreb opened its municipal pools, museums and libraries with free entry for residents over the weekend, and Koprivnica announced free use of its Cerine pools. Similar free‑access initiatives are in place in other Croatian towns. The Adriatic Sea is also warming, encouraging invasive marine species that threaten native fish and shellfish.
Overall, the heat wave is prompting coordinated health advisories, infrastructure adjustments and community‑level cooling efforts across the Balkans.
