Following an exceptionally warm and dry spring, a persistent high-pressure system known as an omega block established itself over Europe in summer 1540. This formation blocked incoming Atlantic air currents for several months, while cool and showery weather prevailed in western Russia, preventing any relief from the heat and aridity across central and western Europe.
From February through the end of 1540, Europe experienced extraordinary warmth and minimal rainfall. Estimated annual temperatures were the highest recorded between 1500 and 2000, and precipitation was the lowest registered until 2025. The event affected France, England, Belgium, the Netherlands, Luxembourg, Germany, Switzerland, Austria, Czechia, Slovakia, Poland, Slovenia, northern and central Italy, and southern Spain.
The relentless heat and drought caused catastrophic impacts on agriculture and human communities across large parts of Europe, contributing to famine conditions. The severity and extent of the disaster were documented in over 220 contemporary chronicles, providing an unusually detailed historical record of the event's effects on both the natural environment and society.
