Conditions at Sandy Beach in March
March: Spring's Transitional Punch
March is the last full month of true winter power, though the energy begins to back off slightly. Average swell height is around 8ft (2.4m) with an average period of 11.3 seconds - still long-period and powerful. The directional distribution is excellent, with WSW (17.4%), SW (14.7%), and SSW (9.6%) dominating and W adding another 5.3%, giving the west-southwest-facing beach close to half of its swell from the optimal quadrant. Offshore winds still blow 53 percent of the time, although the intensity starts to wane; ENE (13.4%) and NE (10.5%) are the workhorse directions. Air temps climb to 2.5°C and water bottoms out at 5.4°C, so it remains a thick wetsuit month, but the surf is consistent and often very good.
