The MSW API aims to support both developers and surfers by opening our data for creative and interesting projects. It gives access to core marine weather data purposed specifically for surfing, but useful for a huge range of activities. Basic access is completely free.

We’ve spent over a decade and hundreds of thousands of pounds developing our systems and infrastructure and we’re now opening them up to developers to build new and exciting product with. Before you get started you need to read the terms and conditions carefully. They not only provide us and you with necessary legal protection they describe how we can work together effectively as partners and also, critically, how you are and aren’t allowed to use our data.

Once you’ve read the terms head over to the sign up section to get an API key and then checkout the forecast overview guide which’ll show you how to get started.
