Poland is experiencing a significant increase in the frequency of heatwaves, with current numbers of hot days already two to three times higher than at the turn of the century. The country is also seeing a rise in “tropical nights,” where temperatures remain high enough to disrupt sleep. Experts indicate these trends are likely to continue, suggesting increasingly extreme heat will become the norm. The escalating temperatures pose potential risks to public health and infrastructure. This shift represents a clear indication of a changing climate within Poland. Authorities are preparing for more frequent and intense heat events in the coming years, and citizens are advised to take precautions during warmer periods. The possibility of 40°C (104°F) temperatures occurring as early as June is being discussed.
