Portugal is grappling with a climate reckoning as extreme heat events reshape its summers. The country recorded its third-hottest June since records began, with temperatures hitting 46.6°C in Mora – a historic high for the month – according to the Portuguese Institute for the Sea and Atmosphere (IPMA).
Record-Breaking Temperatures
A late-June heatwave engulfed the Iberian Peninsula through a 'heat dome' phenomenon, where high-pressure systems trapped hot air from North Africa. IPMA data shows June 2025 ranked as both the third warmest and fourth driest June in Portugal's history, with Mediterranean sea temperatures and parched soils intensifying effects.
Climate Experts Sound the Alarm
Climatologist Jose Alvaro Silva attributes the pattern to climate change: "These events are becoming part of our new climate reality." University of Lisbon's Ricardo Trigo warns future heatwaves could intensify if warm Mediterranean waters and drought conditions persist, creating feedback loops.
Human Cost of Rising Heat
Portugal's health authorities reported 69 excess deaths during the heat alert period, primarily affecting those aged 85+. With seasonal forecasts predicting above-average temperatures through August, officials brace for recurring crises.
Global Implications
While focused on Portugal, this pattern mirrors climate challenges across Asia and beyond. Business leaders note potential impacts on Mediterranean trade routes, while health experts urge heat-preparedness strategies applicable to tropical regions.
