Conditions at Belmar in April
April: East Swell Onslaught
The winter pattern loosens, but April's average height still sits around 4ft (1.2m) with an average period of 7.4s. The swell spectrum shifts dramatically toward the east and southeast: S (17%), E (15%), SSE (14%), SE (12%), and ESE (12%) combine to make this one of the most easterly months of the year, with the favorable ENE/E/ESE/SE quadrant totaling 46%. That means more waves are actually approaching Belmar from a good direction. The catch is wind: ideal offshore flow drops to 33%, and the springtime SSW/SW flow becomes more common, which can add cross-shore chop. Still, spring nor'easters can produce genuinely good surf. Water temps climb to 8.2°C and average air temps reach 8.9°C, signaling the beginning of the shoulder season.
