Conditions at Spessard Holland in April
April: East-Facing Windswell Season
April marks the beginning of the transition away from winter's consistent groundswell. The average height slips to 2-3ft (0.8m) and the period drops to 8.1s. The swell direction remains heavily E/ENE, with E at a dominant 28%, ENE at 21%, NE at 13%, and NNE at 7%. However, much of this is short-period windswell from the strengthening subtropical high, producing playful but disorganized 1-3ft (0.5-1m) surf. The 3-5ft (1-1.5m) class persists, but it is increasingly tied to passing cold fronts rather than distant North Atlantic storms.
Onshore flow dominates: E/ESE/SE winds make up over 33% of the hourly wind observations, and ideal offshore conditions only blow 20% of the time. When the wind does clock into the SSW-SW quadrant ahead of a front, Spessard can turn surprisingly good for an early-season east-coast sandbar. Air temp averages 73°F (22.7°C), water temp is a comfortable 75°F (24.1°C), and the rain clock is ticking upward-bring the spring suit and a rain jacket for dawn patrols.
