The first heatwave of summer 2026 has settled over Île-de-France, and finding a place to cool off in Essonne (91) has become the top priority. We’ve pulled out the swimsuit earlier than planned, as it’s already extremely hot in these early days of summer. Needless to say, the department’s swimming spots are arriving just in time.
Good news for Essonne: there are plenty of spots to cool off, from temporary beaches to leisure centers and outdoor pools spread across the 91. Here are the places already open and those coming online that will stay accessible through the end of August, sometimes into mid-September. In the heat wave, everyone heads for these cool corners with their feet in the water—provided they protect themselves properly and don’t soak up sunlight without protection.
