October: The North Atlantic Roars Back to Life
October is when Manasquan Inlet turns serious. The North Atlantic storm track ramps up quickly and the average wave height rises to 4ft (1.2m), with periods averaging 7.7s. Unlike summer, the swell is no longer just south/southeast windswell; E, ESE, SE and ENE groundswell pulses become a regular occurrence, and the percentage of south/southwest swell shrinks. The wind flow also becomes more winter-like: WNW, NW, W and NNW dominate the offshore quadrants, with 35 percent of the wind deemed ideal for surfing. When an extratropical cyclone deepens off the Mid-Atlantic coast and a following high pressure system delivers west winds, the inlet lines up with clean, powerful head-high-plus waves. The ocean still has some September warmth at 18.0°C, but the air drops to 15.5°C, so the water feels okay as the air starts to sharpen. This is the month to circle on the calendar.
