Scraping Dark Sky Data
Dark Sky is a “scarily accurate” weather forecasting service that offers an app and also helps provide data to thousands of businesses through the Dark Sky API. You can refister for a free API key to start testing the API, and if you need to use it for large quantities of data going forward, you can use their paid API.
Getting Bulk Data
If you’re specifically interested in analyzing bulk data from Dark Sky (compared to accessing it in realtime in a direct consumer-facing app), you’ll want to browse the Dark Sky API Docs and find the endpoint(s) you’d like to pull down data from. At this point, you’re free to write your own code to periodically access the endpoint(s) of your choosing to collect bulk data.
But if you’re requirements are relatively simple and you’d prefer to not write custom code to access Dark Sky data, you can use the endpionts on this page which will access Dark Sky on your behalf and return CSV data from them for instant use in a spreadsheet or database, without having to write custom code.
