Overview

• The season began on April 30 at Kreuzberg’s Sommerbad, followed by openings at Insulaner, Olympiastadion, Wilmersdorf, Wannsee and Gropiusstadt.
• By May 26, just 43,541 visits were recorded compared with 112,096 in the same period of 2024.
• Under tight budgets, only four pools have been heated to about 22 °C, forcing other venues to depend on solar heating.
• This May saw only two days above 25 °C and 19 days below 20 °C, a sharp contrast with ten warm days in May 2024.
• Early-booking and family discounts are still available for online tickets, but the impact of new pricing on turnout remains unclear.
