Ever since Weather Underground (WU) announced its acquisition by The Weather Company, a subsidiary company of IBM, there have been plenty of changes around its transition. One of the most notable being the cessation of its popular API service in December 2018, which meant a significant reduction in Wunderground’s breadth of services.

Although the company still offers data packages on current weather data and forecasts, it no longer provides keys to the weather API. This is a huge blow to thousands of users and organizations who have relied on the Wunderground weather API for years.

Despite this turn of events, Wunderground weather API users can still obtain accurate weather-related information from alternative sources. This post puts together the best Weather APIs you can integrate on your website or mobile app.
