Tempest Almanac

Tempest Almanac is designed exclusively for owners of a Tempest Weather System. It connects to your personal Tempest account and turns your station's weather data into a detailed personal weather almanac.
Go beyond today's temperature and forecast. Tempest Almanac helps you explore what has happened at your own weather station — today, this month, this year, and throughout the history available from your Tempest.
Explore your weather with:
• Current conditions from your Tempest station
• Detailed temperature, humidity, pressure, wind, rain, UV, solar radiation, and lightning information
• On This Day records from your station's history
• Daily, monthly, and yearly weather summaries
• Historical averages for comparison
• Interactive temperature, pressure, wind, and rainfall graphs
• Personal temperature and rainfall records
• Hot-day, freeze-day, and rain-day tracking
• Side-by-side comparisons of days, months, and years
• Apple Watch support, widgets, and complications
• Customizable units and weather thresholds
Tempest Almanac uses your Tempest Personal Access Token to retrieve weather information associated with your station. Your token is stored securely in Apple's Keychain and is not collected by the developer.
Want to explore the app before connecting your station? Demo Mode provides sample weather history so you can experience Tempest Almanac's summaries, records, comparisons, and graphs without connecting a Tempest.
Requirements: A Tempest Weather System and Tempest account are required to use Tempest Almanac with your own weather data. Tempest Almanac is an independent application and is not affiliated with or endorsed by WeatherFlow-Tempest.
