Spain +45,8°C in El Granado – New June Record (!!!), Morocco +46,4°C, Turkey +45,2°C, France +41,5°C
Marek Kučera 
The end of June 2025 has delivered one of the most extreme heatwaves ever recorded for this early in the summer season, with national records tumbling across southern Europe, the Mediterranean, and parts of North Africa. What is unfolding is not just a heatwave, but a climatic event of historic proportions, marked by unprecedented maximum and minimum temperatures, and shocking deviations from seasonal norms.
🌡️ Record-Breaking Temperatures Across Continents
- Spain has rewritten the national climate books, with El Granado soaring to 45.8°C, the hottest June temperature ever recorded in the country. This surpasses all previous benchmarks and highlights the accelerated intensity of Iberian heat events.
- In Morocco, thermometers registered 46.4°C, with another astonishing 43.4°C in Larache, a coastal city on the cooler Atlantic side of the country. This is particularly significant, as such extremes near the ocean were once deemed nearly impossible. The Larache value marks the hottest June day in the city’s history, challenging long-standing assumptions about Morocco’s coastal climate stability.
- Turkey followed with an intense 45.2°C, likely one of the highest values for June in Turkish history
- Portugal recorded a blistering 43.0°C, edging closer to historical thresholds.
- In France, widespread heat engulfed much of the country, with 41.5°C recorded and many local stations surpassing their previous June records. This heatwave is among France’s strongest early-summer episodes on record.
- Even the Azores, known for their cool maritime climate, reported an unseasonably high 28.3°C, underscoring how far-reaching this hot air mass has become, extending far into the Atlantic Ocean.
🌃 Extreme Nighttime Heat
Perhaps even more alarming than the daytime highs are the record-warm nights experienced in parts of the United Kingdom, Greece, Turkey, and the Balkans. In many areas in the Mediterranean, minimum temperatures have failed to drop below 28–33°C, an almost unimaginable situation in regions that typically cool significantly overnight.
These tropical and supertropical nights are physiologically dangerous, offering no relief for vulnerable populations and significantly increasing the risk of heat-related health crises. In places like Athens, Skopje, and Istanbul, the lack of nighttime cooling is being described as “insane” by meteorologists.
⛰️ Airmass Anomaly Reaches the Alps
The intense heat is surging northward, and today, June 28th, meteorologists expect temperatures in Spain to again rise to 43–44°C. Even more extraordinary is the warm airmass pushing into Central Europe, where the freezing level is expected to exceed 5000 meters above sea level. This is an unusual and dangerous meteorological indicator, particularly for glacial and alpine environments, where such high zero-degree isotherms can accelerate melting of snow and ice, trigger avalanches, and disrupt local climates.
⚠️ An Ominous Sign of What’s Ahead
This record-shattering heatwave is a stark reminder of the intensifying global climate crisis. With more than a dozen locations in Europe and North Africa breaking or nearing national records, and with tropical nights becoming more frequent even in temperate zones, scientists warn that climate boundaries are being pushed at an alarming rate.
Meteorologists, climatologists, and health authorities are urging continued monitoring, adaptation planning, and proactive cooling strategies, as the peak of summer has not even begun.
