Conditions at Spiders in March
March: Late-Winter Punch with an Equinox Edge
March is still firmly in the best window, though the transition to spring is beginning to show. Average size hangs around 7ft (2.2m), but the mean period drops to 12.4s, so the swell is slightly less organized than midwinter. The directional spread stays similar - NNW and NW combine for 62 percent, and WNW still adds 9.4 percent - meaning there is plenty of power hitting the west-facing coast. Wind is the weak link: ideal offshore wind time falls to 47 percent, and the strengthening northerly flow starts to puff harder in the afternoons. Air temperatures warm to around 17C, water temps sit at 17.0C, and precipitation is still a factor. Mornings offer the best chance of clean, lined-up conditions before the breeze builds.
