WeatherNext 3 refreshes forecasts every hour

Google DeepMind’s WeatherNext 3 now turns live satellite observations into hourly forecasts, with up to 50% more accurate precipitation predictions a day or more ahead, according to Google’s WeatherNext 3 launch note. The model exposes 5-kilometer surface variables through BigQuery, Earth Engine, and Cloud Storage, making this more than a consumer-weather refresh. Teams building no-code AI workflows should treat forecast freshness as an input contract—but validate regional gains before replacing a local or specialist feed.
