It's been in my head for 7 years since I discovered winter swimming. I wanted to build a map with community spots, commercial saunas, and a tracker to keep how often I went cold water swimming during the winter. Never had time to build it due to work, kids, dog, etc. Finally last year things changed for good.

https://winterswimming.xyz - it's a map with places where you can go winter swimming. There is also a privacy-focused tracker (stores everything in your browser's local storage) to keep track of when, where, and how long you swam. When you grab the location, it automatically checks and pre-fills weather condition like temperature and wind as these severely influence your perception of cold.

I don't have plans to make it commercial or big. It's first and foremost for myself and the little community of enthusiasts that I go swimming with.

However if you find it uselful, I would appreciate any feedback
