Google launches WeatherNext 3, its most advanced AI weather model yet

Google DeepMind and Google Research have unveiled WeatherNext 3, a new AI weather forecasting system the company says is its most accurate global model to date, and it’s already rolling out across Search, Gemini, Maps, and Google Cloud. Weather shapes an enormous range of everyday and high-stakes decisions, from whether to carry an umbrella to how supply chains, farms, and power grids respond to storms, heatwaves, and droughts. While AI has already sped up and sharpened forecasting in recent years, predicting fast-moving, hyper-local weather has remained a weak spot for existing models, largely because they lacked fine-grained detail and struggled to fold in real-time data from sources like satellites.
