On-demand calculations of commonly requested analytics

Rose plots and weather windows, among others, can be downloaded and easily included in your documents.

Continuously-improving metocean data

The portal is constantly being updated with new and improved data, providing you with the best available metocean information around the world.

Take a quick tour!

Get started!

The MetOcean Data Portal enables you to access free analytics and download time series data either through a user-friendly interface or using an API.

Simply place the marker on the map, select a dataset, and extract the data for your area of interest.

You are now able to see, print and download an analytic visualisation through time series plots, rose plots, altimeter comparisons (validation) and more.

Key benefits

The MetOcean Data Portal is aimed for feasibility, planning, design, construction and operation in any offshore or coastal water environment globally.

Here’s what you should know about the portal:

The data is based on extensive wave and hydrodynamic modelling covering the period from 1979 to 2019

Site-specific validation of wind and wave data against satellite altimeter measurements are available, prior to data purchase
A key differentiation is the length of the time series, typically 30-40 years, reducing uncertainty on calculated analytics

Data can be saved in different formats (for example, .MAT, .CVS, .NC, .DFS0), and can be easily embedded in MIKE models (for instance, as boundary conditions)
The hydrodynamics and wave data is generated by MIKE Powered by DHI numerical models, the preferred choice of marine water professionals for more than 30 years
Data can be extracted through an easy to use interface or programmatical using an API (for example; cURL, Python, MATLAB)
