Conditions at Boilers in April
April: The Transition Begins
April is the first true shoulder month. The average swell remains a respectable 6-7ft (2.0m), but the period drops to 10.9s, meaning less push and more chop. The rose is heavily loaded to the NNW at 46.3%, with NW at 23.9% and WNW at 6.7%. Almost no swell arrives from the optimal S/SW/WSW band, so Boilers relies on northern groundswell and windswell mixing over the bank.
Wind becomes the limiting factor: only 25% ideal offshore flow. N winds are strong at 19.7%, and the NNW trades blow 43.6% of the time, often clipping along at 30-50 km/h. This produces bumpy, cross-offshore surfaces in the afternoon. Air temp rises to 18.1°C, water temp sits at 17.1°C, precipitation drops to 0.42mm/day. Chasing dawn is the move.
