Wave climate for La Reunion

“Nouvelle Route du Littoral”

Aktis Hydraulics has carried out a detailed wave and wind climate assessment for the high-way “Nouvelle Route du Littoral”, located above the Indian Ocean on the steep slopes of the Island of La Reunion.

The location of interest is in particular affected by mulitple swell systems coming from the Indian Ocean and around the island from the South-West and South-East originating from the ‘roaring’ forties.

The image below show annual mean wave directional wave variations, but true 2D spectra are in fact required to describe the underlying (uncorrelated!) swell systems that affect the locations of interest.

The images below show wave roses for various locations around the island based on integrated parameters describing the overall sea state.
