  A nested large-scale wave model that covers most of the Atlantic Ocean and
focuses on generating accurate swell conditions for Ireland is presented and
validated over the two years 2016 and 2017. The impact of currents is studied
using the surface currents from the GLORYS product. Currents slightly reduce by
1\% the error of the model compared to altimetry data, but they explain most of
the wave energy at scales less than 50 meters. The variability induced by
currents is found to be more noticeable on the instantaneous fields, up to 50
cm. Track following observations indicate that wave refraction induced by
mesoscale eddies is correctly captured. However, this modulation is of the same
order as a shorter-scale variability appearing in the altimetry data, which
makes it difficult to objectively assess the impact of currents.
