Conditions at Bathtub Beach in March
March: Bigger Periods, Shifting Winds
March is a transition month with a late-winter kick. The average swell height remains 4ft (1.2m), but the period climbs to 8.2s, giving the waves more push and better shape once they hit the reef. NE and ENE swells dominate with nearly 20 percent each, and there is a noticeable bump in 5-8ft (1.5-2.5m) energy from those directions. The catch is a drop in offshore wind frequency to 24 percent, while E and ESE winds become more common as the Bermuda High strengthens. Your best windows are still behind cold fronts, when NNW and NW winds take over and turn the NE swell into organized lines. Air temperatures average 21.9°C, water around 22.8°C, and rainfall increases slightly to 2.65 mm/day, so expect typical spring instability. When it comes together, March can deliver Bathtub's best mix of size and period.
