Weather app with guaranteed accuracy

While general weather apps abound, the Tempest app is different. It feeds real-time observed weather data from your backyard into a machine learning system to dramatically improve forecast accuracy where it matters most – your home. No other weather app or forecast can compare because they don’t start with the weather conditions at your specific location.

Nearcast

Technology™

What makes your Tempest forecast so accurate? It starts with your weather data. In addition to your Tempest observations, we ingest a massive amount of data from satellites, radars, government surface networks, etc. Initialized with our curated data sets, we also run our own high-resolution numerical weather forecast models. We train our AI-based output models to produce accurate point-specific forecasts informed by the observations. The result is a forecast tailored to your exact location.

About the
changing weather

Tempest data, along with all our real-time useful information, is part of data sets which are shared with the National Weather Service (NWS–NOAA) and other met agencies across the world, supporting their mission of predicting dangerous weather and warning the public of potential risks. As forecasting becomes more difficult and weather patterns increasingly erratic, each Tempest helps contribute to a better global forecast.
