About Tomorrow

Tomorrow.io provides a weather data API for developers, offering more than 80 data fields covering core weather conditions, air quality, pollen, fire risk, flood threat, lightning, maritime conditions, soil moisture and temperature, solar irradiation, and road risk. Data is accessible through endpoints including Timeline (point, polygon, or polyline queries from 7 days in the past to 14 days ahead, down to 1-minute resolution), Map (integrable with MapBox, Google Maps, Leaflet, and OpenLayers), Historical (observations since 2000), Route, Alerts, Insights, Locations, Events, and Notifications.

The API is intended for building applications around operational planning, historical weather analysis, threshold-based insights, custom map visualizations, proactive weather event alerts, and route safety for flying, driving, and sailing. Documentation includes a Postman collection, sample code, and recipes covering use cases such as building a weather app, visualizing precipitation on a map, setting up geofenced severe weather alerts via webhook, and using historical data for aviation, logistics, and energy outage retrospection. A GALE AI feature allows asking weather questions and generating weather summaries.
