As part of the continuing professionalization of the services, KNMI has decided to transfer data provision to a secure environment where you can easily retrieve your data free of cost.
KNMI Data Platform and Developer Portal
KNMI has all its (open) data products available through the KNMI Data Platform catalog. The data is made available via APIs. After creating an account on the Developer Portal the corresponding keys for the APIs can be requested. You can also obtain the data anonymously, with an anonymous API key. This key can also be requested via the Developer Portal.
If you want more information about getting started with APIs and how to get started, please read the explanation page.
Do you have questions?
For questions about datasets, APIs and keys, please contact us at opendata@knmi.nl.
