Conditions at Cave in March
March: Late-Winter Punch With Early-Spring Light
March keeps Cave firmly in the late-winter surf window. The average swell is still a robust 7.5ft (2.3m) with an average period of 12.3s, so the ocean retains plenty of power. NW swell dominates the rose at 24.5%, followed closely by WNW at 18.3%, yet the west and southwest swells are the ones that truly light up Cave's southwest-facing banks. The ideal wind score slips slightly to 24%, and NNW wind remains the most common direction at 20.9%, so wind direction is often the deciding factor between a great session and a frustrating one. Warmer air temperatures of 13.4°C and water temperature of 14.7°C still require a solid 4/3 wetsuit, but the added daylight and early spring sunshine make March a favourite among local surfers.
