Google DeepMind and Google Research unveiled WeatherNext 3, an AI model that incorporates real-time satellite data and hourly updates to enhance global weather forecasts.
Google DeepMind and Google Research have rolled out WeatherNext 3, the company’s latest AI‑driven weather‑forecasting engine. The model blends real‑time satellite feeds with hourly updates, delivering higher‑resolution predictions and more precise precipitation estimates. Google says the new system improves rainfall forecasts by roughly 50 % and is 60 % more accurate than its predecessor, WeatherNext 2, which debuted in November 2025.
The upgrade marks a shift from traditional numerical weather prediction (NWP) – supercomputer‑intensive physics simulations that typically lag six hours behind observations – toward a data‑centric approach that can refresh forecasts every hour. By integrating clean‑energy variables, WeatherNext 3 also aims to support power‑grid planning and other climate‑sensitive applications. The model is already embedded in Google’s consumer products, including Search, Maps, Gemini, the Google Maps Platform, and Google Cloud, giving users and developers immediate access to finer‑grained weather data.
Why it matters is twofold. First, faster, more accurate forecasts can improve everyday decisions, from travel planning to agricultural management, while also enhancing emergency‑response readiness. Second, the reduced reliance on costly NWP infrastructure could lower barriers for smaller firms and researchers who need high‑quality weather inputs, potentially reshaping the market for meteorological services.
Looking ahead, the rollout will be closely watched for real‑world performance across Google’s ecosystem and for uptake via the Cloud platform. Competitors may respond with their own AI‑enhanced models, and regulators could scrutinise the use of satellite data and the model’s impact on existing forecasting services. The next few months should reveal whether WeatherNext 3 can translate its laboratory gains into tangible benefits for users and the broader climate‑tech landscape.
