Google Updates Its Weather Forecasts with a New AI Model

Why It Matters

By delivering near‑real‑time, high‑resolution forecasts, WeatherNext 2 gives businesses and consumers more precise weather data for operational decisions, and positions Google as a strong competitor in the emerging AI‑weather market.

Summary

Google unveiled WeatherNext 2, an AI‑powered weather forecasting model that is eight times faster and more accurate than its predecessor, achieving 99.9% accuracy on variables such as temperature and wind. The model uses a Functional Generative Network to generate hundreds of possible outcomes in under a minute on a TPU, enabling hourly forecasts up to 15 days ahead. Google will integrate WeatherNext 2 into Search, Maps, Gemini, Pixel Weather and make it available via Earth Engine, BigQuery and an early‑access API for enterprise customers. The rollout shifts the technology from experimental research to a commercial product targeting energy, agriculture, logistics and transportation sectors.
