Google DeepMind and Google Research released WeatherNext 3 on September 3, 2026, an AI weather model that ingests live geostationary satellite mosaics and station observations to produce hourly forecasts at up to 5 km resolution, about five times sharper than WeatherNext 2's 25 km / 6-hour grid. DeepMind said precipitation scores improved by up to 60% versus NASA IMERG at early leads and that day-ahead rain forecasts in consumer products should be up to 50% more accurate, with new 100-meter wind and solar-radiation fields for clean-energy planning. The model is live in Search, Gemini, Maps, the Maps Platform Weather API, Earth Engine, BigQuery and Cloud Storage.
