API Documentation

The Tomorrow.io Weather API combines traditional weather data sources with new sensing technologies and proprietary modeling to deliver best-in-class weather data, with hyperlocal observations, ground-level tracking, up-to-date data delivery, and minutely forecasting.
Get up-and-running immediately! Grab your private API key here to start querying parameters. Your key carries full privileges so make sure to keep it secure!
Here’s where to find information on how to format your Locations (geometry, latlong, or locationID), Date and Time, Unit System, Delimeters, Nulls, and Timezones for all queries.
Webhooks allow you to receive real-time updates when a specific event occur, like an alert notification for a monitored location or weather condition. Configure your webhooks to integrate the API with dozens of systems.
With more than 60 core weather data layers, you’ll find almost any basic weather parameter you’re looking for, in any location in the world.
This endpoint will allow you to query any weather conditions from any of the data layers by specifying the location, fields, timesteps, and receive a response that includes multiple timelines, one for each timestep – all within a single call to the API. 
Superimpose accurate weather conditions onto an interactive weather map, with support for OpenLayers, LeafLets, and MapBox. 
Predefined locations can be queried in any of the data endpoints, via point, polygon, or polyline geometry for maximum flexibility with bounding boxes. 
Use weather insights to go beyond just the forecast with situational awareness and standardized weather events from many sources, allowing managers to monitor the whole picture across all types of local, regional, and national alerts.
This endpoint will allow you to query for weather events by specifying locations and triggers such that the response includes all values on observations or predictions.
When an Event is generated for an Insight being monitored with an Alert, the system will trigger out Webhook notifications to any user.

Use case examples

Use our Timelines endpoint to query any data points to any locations with just a single call. 
Our advanced alerting system allows you to subscribe locations of interest to national weather advisories in just a few simple steps.
Navigate in peak performance by calling the Route endpoint to properly calculate ETAs and avoid weather risks, integrating with popular navigation services like Google and Mapbox.
The events endpoints allow anyone to pull a collection of all forecasted weather events, using custom conditions or insight categories. 
Log real-time weather by calling our API And logging resolved weather data in a spreadsheet, for data science or climatology use cases. 
Visualize weather data and interact with weather maps, charts, and tables using Python and Jupyter Notebooks.
Create a simple GUI weather widget using Python on Raspberry Pi boards.
