WeatherNext 3 API and Data Access
Once manual exploration stops scaling, the forecast has to arrive in your own system. There are two routes: pull the research datasets directly from Google's cloud products, or call an interface that returns forecast answers for a location and a time range. This page covers both, and the download guide covers what the data actually contains.

From sign-in to your first forecast call
Four steps take you from a manual forecast to an automated one.
Create an account
Sign in with Google, then pick a plan. Every monthly plan starts with a 7-day free trial and includes forecast credits.
Generate an API key
Create and label a key in your settings so you can rotate or revoke it without disturbing other integrations.
Request a forecast
Ask for a location, a variable set and a time range. Requests take coordinates or place names and return the hourly fields you selected.
Automate the workflow
Schedule the call so forecasts land in dashboards, alerting rules or planning tools before anyone has to ask for them.
What you can request through an API
The interface returns the same hourly forecasts you see in the workspace, which means one integration covers planning, alerting and reporting rather than three separate data pulls.
Point forecasts
Hourly series for a coordinate or named place, ready to join with an asset register.
Selected variables
Precipitation, temperature, humidity, wind, radiation and cloud cover, chosen per request.
Time ranges
Request the window you plan over instead of pulling a fixed daily summary.
Credits you control
Usage draws on the same monthly forecast credits as the workspace, so cost stays in one place.
Research data channels from Google
If you need the underlying fields rather than an answer, Google publishes forecast data through its own cloud and developer products.
BigQuery
Query forecast tables directly and join them with your operational data in SQL.
Earth Engine
Combine forecast layers with satellite imagery and land data in geospatial analysis.
Cloud Storage
Retrieve bulk files when your pipeline needs raw arrays rather than query results.
Google weather APIs
Developer-facing weather data for products that already sit on Google's platform.
Unified forecast API
One key and one contract from this platform instead of separate integrations per source.
Documentation
Variable names, units, time handling and credit behaviour, so your integration matches how the model actually reports.
