Where the wind resource is.
SEAI’s modelled mean wind speed at 50 metres above ground, based on 2001–2010 conditions. This is a long-term resource map, not today’s weather or a project forecast.
Select a point on the map or enter coordinates. Zoom buttons change the view; the coordinate lookup works at every zoom level. Blank cells are outside the source coverage.

How to read this map
Speeds are in metres per second. The source height is 50 metres above ground. Modern turbines may operate at different heights and locations; this map is not a prediction of their output or a substitute for a site assessment.
The original model covers 2001–2010. The published bulk data was last modified on 23 July 2021; newer catalogue metadata does not make the underlying model newer. We transformed the source coordinates from Irish Transverse Mercator (EPSG:2157), simplified the polygons and sampled an approximately 1–2 km display grid. The derivative is deliberately less detailed than the original.
The selected value comes from that display grid. A filtered-out cell still has its original lookup value; a blank cell has no value. No missing area is filled with an invented estimate.
