Weather History API

Get insight into historical weather like never before with our affordable historical weather API's!

With our historical weather API you can access up to 10 years of historical weather data of over 38,000 stations worldwide! Our weather data is real, backfilled, and quality controlled. A historical weather API request will give you real verifiable data for any location, and time period you request. We currently have both hourly, and daily level historical data.

Additionally, for users that need large volumes of data, we have a bulk historical weather API that allows for retrieval of multiple years worth of data at once! (1 year hourly historical data per request, no limit for daily historical data per request)

Below is a description of all of the fields our weather history API returns. Checkout our interactive Weather API swagger documentation for examples, and further clarification.
