How it Works

Weather observations stream instantly from the solar-powered, wireless Tempest station through WeatherFlow’s data processing center. Tempest performs quality control inspections on raw station sensor data, and may apply calibration corrections as needed.

WeatherFlow guarantees the Tempest System will produce a better forecast for the specific location in which it is installed. If you believe the forecast provided by your Tempest System is not measurably superior to forecasts publicly available elsewhere, you may request a full refund for the Tempest System up to 8 months after the date of purchase.
