Spain's state meteorological agency, Aemet, has confirmed that Monday and Tuesday were the hottest June days on record for mainland Spain since at least 1950. The announcement comes as a severe heatwave grips large parts of southern Europe, prompting authorities to take emergency measures.
Temperatures soared above 40°C in several cities, including Seville, Córdoba, and Granada, with the mercury peaking at 44°C in some areas of Andalusia. The previous June record, set in 2019, was surpassed by a significant margin, underscoring the intensifying impact of climate change on the Iberian Peninsula.
Heatwave Prompts Cancellations and Health Warnings
In response to the extreme conditions, local governments across Spain have cancelled San Juan bonfires across half the country, a traditional midsummer celebration that typically involves large outdoor fires. The decision was made to reduce the risk of wildfires and protect public health, as the combination of high temperatures and dry vegetation creates a tinderbox environment.
Health authorities have issued red alerts for several regions, urging residents to stay indoors during peak heat hours, stay hydrated, and check on vulnerable neighbours. Emergency services have reported a spike in heat-related calls, though no fatalities have been confirmed so far.
The heatwave is not confined to Spain. France recorded its hottest day of the year on Tuesday, with temperatures exceeding 40°C in parts of the Rhône Valley. In Italy, the health ministry activated its heatwave warning system for 14 cities, including Rome, Florence, and Bologna. Portugal's Instituto Português do Mar e da Atmosfera (IPMA) has also warned of temperatures up to 45°C in the Alentejo region.
Climate Context and Long-Term Trends
Scientists at Aemet have linked the extreme heat to a persistent high-pressure system over the western Mediterranean, which has drawn hot air from North Africa. However, they also stress that such events are becoming more frequent and intense due to global warming. Spain has experienced a series of record-breaking heatwaves in recent years, including a devastating episode in 2022 that caused over 4,600 excess deaths across the country.
The European Union's Copernicus Climate Change Service has noted that June 2024 is on track to be among the hottest Junes on record for the continent as a whole. This trend raises urgent questions about the bloc's preparedness for climate-related risks, particularly in southern member states that are most vulnerable to heatwaves, droughts, and wildfires.
In Brussels, the European Commission has been under pressure to strengthen its climate adaptation strategy. Twelve EU member states have called for post-2030 green funding to help ease the energy transition and bolster resilience against extreme weather. Spain, which currently holds the rotating presidency of the Council of the EU, has been a vocal advocate for increased investment in climate adaptation measures.
Impact on Energy and Infrastructure
The heatwave has also put strain on Spain's energy grid. Demand for electricity surged as air conditioning use spiked, pushing prices higher on the wholesale market. Red Eléctrica de España, the grid operator, has warned of potential supply constraints if the heat persists. Meanwhile, renewable energy production from solar panels has been strong, but wind generation has dipped due to calm conditions.
Transport infrastructure has been affected as well. Renfe, the national railway operator, has imposed speed restrictions on several high-speed lines to prevent tracks from buckling in the heat. Airports in Seville and Málaga have reported minor delays as ground crews struggle with the conditions.
As the heatwave continues, meteorologists expect temperatures to remain well above seasonal norms until at least the end of the week. For millions of Europeans, the immediate concern is staying safe, but the broader challenge of adapting to a warming continent remains pressing.
