About the project

A narrow, inspectable reference for outdoor sauna planning.

OutdoorSteamSauna.com publishes climate comparisons, energy-cost scenarios, heater-sizing tools and practical planning guides for outdoor traditional sauna projects in the United States.

The project is built around primary public data from NOAA/NCEI and the U.S. Energy Information Administration. Each city record exposes the selected station, geographic distance, source period, update date and formula used to derive the score.

What we do

  • Maintain a reproducible city-level climate and electricity dataset.
  • Publish machine-readable CSV and JSON files.
  • Explain where calculations are estimates and where data are unavailable.
  • Correct material errors publicly.
  • Keep commercial recommendations outside research formulas.

What we do not do

We do not approve products, design electrical systems, issue permits, predict site-specific performance or substitute for a manufacturer, electrician, engineer or local authority.

Commercial separation

The site contains a clearly labeled recommended-retailer page. Retail relationships and compensation are not inputs to city scores, research findings, rankings or calculators.
