Weather Lab is an interactive website developed by Google DeepMind and Google Research for exploring AI weather forecasts. It provides a map-based interface for visualizing global forecast layers, tracking tropical cyclones with predicted and observed tracks, and downloading experimental cyclone forecast data.

Global forecasts
Weather Lab visualizes gridded global weather layers from the following models:
| Model | Variables | Time Step | Forecast Type | Horizon |
|---|---|---|---|---|
| WeatherNext 3 | 2m temperature, total precipitation, 10m wind speed, sea level pressure | 1 hour | Ensemble (64 members) — displays ensemble mean | 15 days (6-hourly) / 48 hours (interim hourly) |
| WeatherNext 2 (FGN) | 2m temperature, total precipitation, 10m wind speed, sea level pressure | 6 hours | Ensemble (64 members) — displays ensemble mean | 15 days |
| Global MetNet | Precipitation | 15 min | Deterministic | 12 hours |
Cyclone tracking
Weather Lab tracks tropical cyclones using WeatherNext Cyclones (Google's AI cyclone model) alongside ECMWF's ENS and HRES as independent baselines. Observed ground-truth tracks are sourced from NHC/JTWC TCVitals (real-time) and IBTrACS (historical). You can compare model predictions, view ensemble member tracks, and inspect deep-dive charts for individual storms.
For more on the research behind WeatherNext Cyclones, see the Nature publication and the blog post.
Download cyclone forecasts
You can download experimental cyclone track predictions from Weather Lab in CSV or ATCF format. Downloads include predicted tracks (position, intensity, timing), ensemble member tracks, and paired observed tracks for verification. Data is available from approximately 2023 to present.
