Most offshore wind turbine structures are built with monopile type structures where some marine operations are conducted nearby. Therefore, proper wave estimation around the monopile is needed to assure safe marine operations. The trend of increasing monopile's diameter also adds the need to investigate the wave field around the increased monopile diameter. Experimental campaigns of wave field around a monopile in irregular incident waves with different steepness are reported in this study to extend avalaible experiments which focused mostly on the runup of cylindrical structures. Wave elevations at two radial positions and six angular positions around the monopile are highlighted. The results are processed to obtain the Linear Transfer Function of wave field around the monopile and the exceedance probability of the crests and wave height of the waves. Linear solution is seen to be able to capture the wave height but the crests exceedance probability.
