March: Spring Transition with More Southern Energy
March begins to shift the energy south. The average swell height eases slightly to 3.9ft (1.2m), while the average period stays at 6.9s. The wave rose now clearly favors S (12.8%) and SSW (12.4%), with SSE (8.5%), ESE (8.4%) and SE (7.9%) offering plenty of secondary energy. This is a good directional setup for the south-facing beach, but the heights are often in the small-to-fun range of 1-3ft (0.5-1m), with only occasional 5-6.5ft (1.5-2m) pulses. Winds are transitional: SW/WSW at 8.8% and 7.5%, with SSW at 7%, bring more onshore flow, while WNW (10.8%), NW (10.6%) and NNW (10%) still send cold fronts across Long Island. Ideal wind hours remain low at 11%. Water temperature is a cold 4.4°C, air averages 3.6°C, and rain increases to 3.86mm/day. Late-month frontal passages can deliver the first good combination of direct south swell and offshore northwest wind.
