Tempest Almanac

Your Tempest has been collecting your weather. Tempest Almanac helps you explore it. Tempest Almanac is designed exclusively for owners of a Tempest Weather System. Connect your personal Tempest account and turn your station’s weather data into a detailed personal weather almanac. Go beyond current conditions and forecasts. Look back at what happened at your own weather station today, this month, this year, or throughout its available history. Discover records, compare seasons, explore trends, and see how today measures up against the weather you’ve experienced before. Explore your weather: • View current conditions from your Tempest station • Explore temperature, humidity, pressure, wind, rain, UV, solar radiation, and lightning data • Rediscover past weather with On This Day • Review daily, monthly, and yearly summaries • Compare conditions with historical averages • Explore interactive temperature, pressure, wind, and rainfall graphs • Discover your personal temperature and rainfall records • Track hot days, freeze days, and rain days • Compare days, months, and years side by side • Stay connected with Apple Watch, widgets, and complications • Customize units and weather thresholds Try it before connecting Demo Mode provides sample weather history so you can explore Tempest Almanac’s summaries, records, comparisons, and graphs without connecting a Tempest station.

Your token is stored securely in Apple’s Keychain and is not collected by the developer.
