Spain is experiencing its first official heatwave of 2026, with temperatures reaching around 40 degrees Celsius in Madrid on Sunday. Local residents and tourists report struggling to cope with the heat as conditions intensify. The heatwave marks the start of an extreme-weather period monitored by Spanish authorities, with forecasts indicating sustained hot temperatures rather than a brief spike. Reports note that the highest readings occur during peak daytime hours, raising concerns about discomfort and health risks, particularly for people spending extended time outdoors. While the focus of coverage is on Madrid, the heatwave designation applies to broader conditions across Spain rather than a single city. The reports emphasize the impact on everyday activities, with people adjusting plans to manage the heat. Authorities typically issue guidance during such events, and the official classification signals that the weather is expected to persist and meet specific thresholds for extreme temperatures.
