April: Autumn Winds Get Favorably Sharp
April is the gateway to Haast's premium surf window. Average wave height sits at 4ft (1.2m), period at 11.4s, and the ideal offshore wind percentage climbs to 35% - enough for regular clean days. The W direction still leads with 40% of all swell, but the more favorably aligned WNW (14.5%), NNW (10.7%), and NW (8.4%) sources are well represented. Wave heights cluster in the 3-5ft (1-1.5m) and 5-6.5ft (1.5-2m) bands, giving the exposed NW-facing beach plenty of shape. Wind observations show WSW as the dominant direction at 20%, with SW at 9%, and crucially a much smaller chunk of N/NW onshore flow than in summer. Air temps have cooled to 10.8°C, water is still pleasant at 14.8°C, and rainfall is 6.05 mm/day. The result: April often delivers multiple all-day offshore sessions on consistent groundswell.
