For all publicly available raw and cleaned data from meteorological masts and LiDAR systems used to measure wind resource for offshore wind developments in England, Wales and Norther Ireland, please follow this link in the first instance.

Details of the data that are available on the Marine Data Exchange are below (last updated July 2019):


If you can't find what you're looking for, please contact mde@thecrownestate.co.uk. 

Some of the reasons why data that you are looking for isn't yet available have been outlined below.

We don't release wind data collected in the last two years 

Whilst we require wind farm developers to provide The Crown Estate with data, we also recognise that the wind is what makes a wind farm work commercially. Therefore there is a commercial sensitivity around wind speed data for the owners and developers of wind farms. To address this we agree a 2 year moratorium on the release of wind data.

Rest assured though, once this 2 year period is over, we endeavour to release the data as soon as practicable, subject to discussions with the owners of the data of course.

We don't have the rights to access it

This usually applies to older data that pre-dates our contractual requirements to provide the data to us. Therefore we have no licence to access the data.

The owner / operator of the data hasn't yet provided it to us

We work with owners / operators to ensure a smooth supply of data to us, but sometimes it can take a little longer than expected. We're working on this and aim to have a full and up-to-date set of data, released regularly to the public.

The data cannot be retrieved 

This is often the case for older data which were not provided at the time. We have made reasonable steps to try and retrieve the data, but the time that has passed since it was collected means that it has been lost.
