Portugal recorded its highest-ever temperature for the month of May this week, as an intense early-season heatwave swept across the Iberian Peninsula and pushed mercury levels to unprecedented heights. Meteorologists at the Portuguese Institute for Sea and Atmosphere (IPMA) confirmed that temperatures in several regions soared past 40 degrees Celsius (104 degrees Fahrenheit), marking a significant departure from historical climate norms for the spring season.
A Historical Shift in Climate Patterns
The record-breaking heat is part of a broader, concerning trend of rising temperatures across Europe. Scientific data from the Copernicus Climate Change Service indicates that the continent is warming faster than the global average, leading to more frequent and intense heat events during the shoulder seasons of spring and autumn.
Historically, May in Portugal is characterized by mild, temperate weather ideal for agriculture and tourism. This year, however, a plume of hot, dry air originating from North Africa has stagnated over the region, effectively creating a dome of heat that has trapped high temperatures and suppressed typical Atlantic cooling breezes.
