Google DeepMind's WeatherNext 3 AI model delivers hourly, 5km-resolution forecasts, improving precipitation accuracy by up to 50% and integrating across Google

Google DeepMind and Google Research have launched WeatherNext 3, an AI-powered global weather forecasting model that improves precipitation forecast accuracy by up to 50% for day-ahead predictions [1]. The new model generates hourly forecasts with a 5-kilometer resolution, a significant upgrade from its predecessor's 25-kilometer grid and six-hour updates, and is now being integrated across Google's core products, including Search and Maps [1, 2].

| At a glance | |
|---|---|
| Company | Google DeepMind / Google Research [1] |
| Product | WeatherNext 3 AI weather model [1] |
| Key Improvement | Up to 50% more accurate precipitation forecasts [1] |
| Resolution | 5-kilometer temperature and humidity predictions [1] |
| Update Frequency | Hourly forecasts [1] |

## Enhanced Forecasting Capabilities

WeatherNext 3 leverages live geostationary satellite data and trains on weather station observations to provide more detailed and frequent updates, particularly for rapidly changing and localized weather events like rain and snow [1]. Google states the model can deliver up to 50% more accurate precipitation forecasts when planning a day or more ahead, and evaluations showed improvements of up to 60% against certain precipitation benchmarks [1]. The model's 5-kilometer resolution for temperature and humidity predictions marks a five-fold improvement in detail compared to WeatherNext 2's 25-kilometer grid [1].

The model also forecasts variables such as wind speeds, cloud cover, and solar radiation, supporting applications beyond daily planning, including agriculture and renewable energy [1, 3].

| Feature | WeatherNext 2 | WeatherNext 3 |
|---|---|---|
| Update Frequency | Six-hour updates [1] | Hourly updates [1] |
| Resolution (Temperature/Humidity) | 25-kilometer grid [1] | 5-kilometer resolution [1] |
| Data Sources | Unspecified [1] | Live geostationary satellite data, weather station observations [1] |
| Precipitation Accuracy | Baseline [1] | Up to 50% more accurate for day-ahead forecasts [1] |

## Integration and Google's AI Strategy

WeatherNext 3 is being rolled out globally and integrated into Google Search, the Gemini app, Google Maps, Google Maps Platform, Earth Engine, and Google Cloud [1, 2]. This integration aligns with Google CEO Sundar Pichai's vision for Search to evolve from a source of "ten blue links" to a "task-based experience" that helps users accomplish tasks and make decisions [2]. The shift reflects a broader trend towards AI-based weather forecasting, which complements traditional physics-based systems [1].

## What to watch

*   **Global rollout progress:** Monitor the full integration of WeatherNext 3 across all listed Google platforms and its impact on user experience [2].
*   **Third-party evaluations:** Observe independent comparisons and benchmarks of WeatherNext 3's performance against other leading AI and traditional weather models [1].
*   **Application in specific sectors:** Track adoption and reported benefits of WeatherNext 3 in specialized fields like agriculture and renewable energy [1].

The launch of WeatherNext 3 underscores Google's commitment to embedding advanced AI capabilities into its core products, aiming to transform how users interact with information and make daily decisions by providing more precise and timely data [2].
