Google has taken a major leap forward in weather forecasting with the release of its latest AI-based system: WeatherNext 2. Capable of generating forecasts eight times faster than traditional models, WeatherNext 2 is designed to equip industries and individuals with more accurate predictions for critical decision-making.
What is WeatherNext 2?
WeatherNext 2 is an AI-powered weather forecasting tool developed by Google DeepMind. Unlike conventional forecasting models that require hours to compute scenarios, this system produces hundreds of global forecasts in under a minute using a specialized chip called the Tensor Processing Unit (TPU). This unprecedented speed allows for more frequent updates, an essential feature during extreme weather events.
Advanced Technology for Improved Accuracy
The development of WeatherNext 2 relies on a proprietary modeling approach called Functional Generative Networks (FGN). This breakthrough technique improves the forecasting model’s ability to predict interconnected variables, such as temperature, wind, humidity, and pressure, across broader regions. In fact, the system is six times more detailed than its predecessor, enabling one-hour prediction intervals instead of the standard six-hour updates.
According to Google, the new model produced better results in almost every variable tested, with an 8.7% improvement in accuracy for average-pooled Continuous Ranked Probability Scores (CRPS). These advancements are particularly notable in areas such as cyclone tracking, where prediction errors were reduced, offering up to 24 hours of advanced warning between three- and five-day forecasts.
Applications Across Google’s Ecosystem
WeatherNext 2 has already been integrated into several Google services, including Search, Gemini, Pixel Weather, and the Google Maps Weather API. This integration ensures that users accessing these platforms receive real-time, precise forecasts that improve their day-to-day planning and enhance safety during extreme weather conditions.
“We rely on accurate weather predictions for critical decisions—from supply chains to energy grids to crop planning,” noted Peter Battaglia, a Google DeepMind research scientist. With WeatherNext 2, extreme weather events can now be tracked more effectively, helping businesses, governments, and individuals make timely decisions to mitigate risks.
Why Better Forecasting Matters
The increasing frequency and severity of natural disasters due to climate change make accurate weather forecasting more critical than ever. With WeatherNext 2, Google aims to provide a powerful tool for better disaster preparedness. From agriculture to renewable energy planning, this technology promises to transform how we respond to changing environmental conditions.
AI-Powered Solutions for Everyday Use
Products like Google’s Pixel Watch now integrate WeatherNext 2 technology to offer seamless weather updates on the go. With improved accuracy, users can track localized weather forecasts, ensuring they’re always prepared, whether they’re out for a daily jog or planning an outdoor event. Check out the Pixel Watch for a smartwatch that combines cutting-edge technology with everyday usability.
Looking Ahead
The rollout of WeatherNext 2 is just the start. Google plans to extend this technology across its platforms and continue refining it to navigate the complexities of extreme weather better. As Akib Uddin, WeatherNext Product Manager, said, “By making better weather predictions, we’re able to help everyone.”
