Google will make weather forecasts more reliable with WeatherNext 3

Google will now offer more reliable weather forecasts thanks to WeatherNext 3, a new artificial intelligence model. The system is designed to significantly improve the accuracy of Google’s weather predictions and provide more detailed information about local conditions.

Key improvements

WeatherNext 3 updates forecasts hourly and utilizes localized data, which is particularly important when weather conditions change rapidly. Rain and snow forecasts are expected to be up to 50% more accurate when made with a day or more of advance notice.

Comparison with previous models

WeatherNext 2 provided forecasts every six hours with a resolution of approximately 25 kilometers. The new model can generate hourly forecasts and achieve a resolution of up to 5 kilometers in certain conditions, allowing for better differentiation between nearby areas with potentially different weather patterns.

Real-time satellite data

Google has integrated real-time satellite observations into WeatherNext 3, enabling the system to utilize more current atmospheric data instead of relying solely on simulations that can be several hours old. The company emphasizes improvements in precipitation forecasts, stating that WeatherNext 3 can enhance accuracy by up to 50% for rain and snow predictions made at least a day in advance.

Availability

WeatherNext 3 is now available on Google Search, Gemini, Google Maps, and various developer and business services, starting today.
