Overview
- Water‑engineering specialists from Helmut‑Schmidt‑University measured flow and substrate on November 6, and the city is waiting for their analysis.
- Operational tweaks, including increased inflow and a short “kickstart,” failed to rebuild the wave, and below‑normal Isar supply has paused further steps this weekend.
- A working hypothesis is that the cleaning removed sand, gravel and moss needed for wave formation, with surf advocates citing roughly 1.25 meters of water versus a ~1.40 meter target.
- Surfers mounted unauthorized night interventions with wooden boards that briefly produced a surfable wave before conditions reverted, and officials stress such actions are illegal.
- The outage affects a flagship Munich attraction, and the Surftown Muc surf park is offering one free session to verified Eisbach surfers through the end of November.
