Google WeatherNext 3 sets a new benchmark for AI weather forecasting

Homepage > News > Business > Google WeatherNext 3 sets a new benchmark for AI weather forecasting Google DeepMind and Google Research have introduced WeatherNext 3, an advanced AI-powered global weather forecasting model engineered to deliver localized, real-time climate intelligence at unprecedented resolution. By directly ingesting live geostationary satellite mosaics and real-world ground station data, WeatherNext 3 eliminates traditional reliance on slow, compute-heavy numerical approximations. The result is an operational system that produces fresh forecasts every hour of the day at up to 5-kilometer spatial resolution—roughly five times sharper than its predecessor. Key Breakthroughs & Capabilities: Continuous Hourly Forecasting: Generates new predictions every hour, providing vital lead time as storms, fronts, and extreme weather develop rapidly. Ultra-High Resolution: Resolves surface temperature and moisture down to 5 km (0.05°) and surface winds to 10 km (0.1°), delivering hyper-local precision even in traditionally underserved areas. Superior Precipitation Accuracy: Cuts error metrics by up to 50% on key precipitation benchmarks compared to traditional numer...
