Seville, known as the “frying pan of Spain,” is no stranger to scorching heat, with summer temperatures that can make outdoor activities unbearable. Climate change is exacerbating this issue, leading to earlier and more intense heat waves. In June 2025, Spain experienced record-breaking temperatures, with Huelva reaching a scorching 46 degrees Celsius, marking the hottest June on record.
Projections suggest that by 2050, Seville could face even more extreme conditions, with peak summer temperatures soaring to 50 degrees Celsius and a significant reduction in rainfall. To combat these challenges, the city has embraced innovative water-based solutions to tackle rising temperatures. Seville’s efforts have not gone unnoticed, as the city recently won the Haciendo misión competition for its strides in climate adaptation.
One notable project in Seville is the Cartuja Qanat, where researchers have revived an ancient Persian cooling technique to combat the heat. By implementing underground canals that circulate cooled groundwater, the project has successfully lowered temperatures in the area by several degrees. This sustainable approach has garnered international attention, with visitors from around the world coming to learn from Seville’s example.
In addition to the Cartuja Qanat project, Seville has introduced bioclimatic air conditioning systems in schools to provide a cool and comfortable learning environment for students. These systems, which rely on water evaporation and solar power, have been installed in over 450 schools across the region, significantly reducing energy consumption and improving student well-being.
Furthermore, Seville is reshaping its urban spaces to mitigate the urban heat island effect, implementing strategies such as shading, reducing asphalt surfaces, and using light and permeable materials. Projects like the Life Watercool initiative on Cruz Roja Avenue aim to cool urban areas through evapotranspiration, utilizing runoff water to irrigate green spaces and provide fresh air circulation through vertical vents.
Seville’s comprehensive approach to combating extreme heat serves as a model for cities worldwide grappling with the impacts of climate change. By embracing sustainable solutions and innovative technologies, Seville is leading the way in creating resilient and livable urban environments for the future.
