For those visiting museums, it may be worth paying the entrance fees, as these locations often maintain lower temperatures to protect valuable artwork. In Paris, options such as the Musée Marmottan Monet and the Musée de Carnavalet can be particularly refreshing. Additionally, in Spain, the Center of Contemporary Culture and Museum of the History of Barcelona are designated climate shelters, offering haven from the summer heat.

For travelers venturing across Europe during this heat wave, being informed and strategic about where to find respite can enhance the summer experience considerably.
