The Wellington region is well known for being windy. The Cook Strait has a wind-funnelling effect, which leads to a high frequency of strong winds around the southern coast, and the rugged landscape results in local variations in wind direction and strength.
Wind records from Cape Palliser and Castlepoint show that Wellington's Wairarapa coast is among the windiest spots in New Zealand.
