You may have heard that Dark Sky (the beloved weather app for iOS) was acquired by Apple and its accompanying developer API will be shut down soon, which left a lot of devs scrambling for alternatives. Enter the PirateWeather API:

Weather forecasts are primarily determined using models run by government agencies, but the outputs aren’t easy to use or in formats built for applications. To try to address this, I’ve put together a service (built on AWS Lambda) that reads public weather forecasts and serves it following the Dark Sky API style.

It’s in beta at the moment, but it appears the author has put a lot of thought into it.
