The number of permitted swimming zones in Moscow has decreased

I'm not sure which specific period or event you're referring to - information about beach reductions in Moscow could be connected to different moments. But generally speaking, here's the situation: the number of officially permitted swimming zones does vary from year to year. It depends on water quality checks, beach conditions, maintenance work, and sanitary regulations. Not all water areas where people like to swim (like near docks or under bridges) get official status as safe zones.

During summer seasons, beaches are usually allowed at the main water bodies - Kolomenskoye park, Serebryany Bor, the Yauza riverbank near Muzeon, Krylatskoe. But the list can shrink if water quality problems are discovered or repair work starts. Over the past few years, beaches on the Moscow River have been closed because they have low cleanliness ratings, although this is a changing situation.

If you're talking about something really recent from 2026, I'd recommend checking the official city hall website or the local water utility - they publish the current list of permitted swimming zones there with reasons for closures.
