Heatwave reaches Hesse as outdoor pools open with new loungers, AI cameras and largely stable admission prices
After a chilly, rainy start to the season, Hesse’s open-air swimming pools are welcoming the first summer heatwave. Operators have added relaxation loungers, e-bike charging and AI-assisted surveillance, while keeping most ticket prices unchanged.
A delayed but hopeful start
After weeks of mixed weather, all outdoor pools across Hesse are now open and expecting a surge in visitors. Operators in Frankfurt, Kassel, Fulda, Bad Hersfeld and elsewhere say that even a few hot days can more than offset a wet June. In Fulda, rainy days drew as few as 550 guests, while sunny days regularly attract 4,000. The pattern was similar in Frankfurt and Kassel, where indoor pools absorbed some of the displaced swimmers.
It has repeatedly been shown that a few hot weeks more than compensate for rainy weeks at the beginning of the season.
May already offered a foretaste: Fulda’s visitor numbers more than doubled compared with the same month in 2025, and Frankfurt’s pools have also seen twice the attendance so far in 2026. All seven of Frankfurt’s outdoor pools opened on Monday, just in time for the predicted 30 °C days.
Prices stay mostly level
Despite rising operating costs, many municipalities have held the line on admission fees. An adult day pass costs EUR 4.50 in Bad Hersfeld, EUR 4.70 in Fulda (up 10 cents), and EUR 5.00 in Frankfurt and Dieburg, unchanged for years. Kassel’s Auebad, which boasts two large slides, charges EUR 7.50, while two smaller pools in the city cost EUR 3.00. The Seedammbad in Bad Homburg, with its eleven pools, asks EUR 8.50 – the same as in 2025.

What’s new this summer
Pools used the spring to scrub, renovate and add amenities. Fulda’s Rosenau pool introduced new relaxation loungers and changing rooms, and now offers free e-bike battery charging for guests. Kassel’s Auebad is rolling out AI-powered surveillance in its outdoor area, after a successful trial indoors, to help lifeguards spot dangerous situations earlier.
After the rather changeable weeks so far, we are looking forward to finally experiencing a regular outdoor pool operation with the corresponding number of visitors.
The Seedammbad in Bad Homburg, which had its start delayed until 15 May by a large car park fire, is also expecting a boost from the warm weather.
