What is WeatherNext 3?
WeatherNext 3 is Google DeepMind’s latest AI weather forecasting model designed to deliver faster, higher-resolution, and more accurate global predictions. It improves on earlier versions by using real-time satellite and observational data to generate forecasts every hour instead of every few hours, with much finer spatial detail. The model can better predict events like rainfall, wind, and temperature—even in regions with limited data—while significantly boosting accuracy, especially for precipitation forecasts. WeatherNext 3 represents a major shift toward AI-driven weather systems that complement traditional physics-based models with faster insights and more granular predictions.
Engineered around the concept of “Rapid weather prediction at unprecedented resolution,” WeatherNext 3 breaks free from the ~6-hour data lag inherent in traditional Numerical Weather Prediction (NWP) analysis. By ingesting a continuous mosaic of live geostationary satellite observations and training against raw weather station measurements, the model refreshes forecasts every hour. It produces multi-resolution outputs reaching down to 5-kilometer (~0.05°) resolution for surface temperature and moisture, 10-kilometer resolution for solar radiation and precipitation, and 25-kilometer resolution for upper-air atmospheric fields. WeatherNext 3 provides up to a 15-day outlook via a 64-member probabilistic ensemble and is currently powering weather insights across Google Search, Gemini, Google Maps, Google Cloud, BigQuery, and Earth Engine.
