Conditions at Cap Gris-Nez in March
March: The NE Swell Window Opens
March marks a subtle shift. The average swell height eases to 2.5ft (0.8m) and the period to 5.2s, but the optimal direction window expands to 33% of the wave rose. NE swell jumps to 14.2%, NNE to 8.7%, and NNW still contributes 4.6%, giving the north-facing beach far more chances to see energy. However, most of that NE/NNE swell is in the 0-3ft (0-1m) bins, with only a few 5-6.5ft (1.5-2m) readings. Winds become more variable: WSW (13.8%) and SW (12.8%) are common, while NE (8.9%) and NNE (5.9%) also push in from the bad onshore direction. Ideal surf remains at 6%. Water holds at 7.7°C, precipitation drops to 1.57mm/day, and air temps slowly climb. March is the first month where you might find a clean NE swell with light SSW wind - a real surf session, albeit on the small side.
