About Weather API
The outside signal that moves real demand.
A weather feed exposes a few standard things over a REST API: current conditions, hourly and daily forecasts, historical observations, severe-weather alerts and a list of resolvable locations by lat-long, postcode or city. Most providers cover the same global grid and refresh on a fixed cadence. The choice between them is mostly about coverage depth, history length and licensing terms.
The reason to land weather in a warehouse is that the value is in the join. Temperature next to terrace covers, rainfall next to bike-shop foot traffic, wind speed next to solar yield, a heat alert next to call-centre volume. As a standalone dashboard a weather widget tells you what you can see out the window. Joined to your sales, ops and energy data, it tells you how much of the variance you have been calling random is in fact the weather.
