Conditions at Belharra in March
March: Power Waning, Windows Narrowing
March marks the first step down in energy: average swell height drops to 6ft (1.8m) and period to 12.1s, yet the swell direction is actually the most dominated by the NW/WNW quadrant of the year - NW 37.5% and WNW 26.5%, with NNW 10.7%. So the reef still sees plenty of lined-up, long-period swell. The catch is wind. Ideal S/SSW offshore conditions now only run 30% of the time, while W/WNW/NW onshore winds are on the rise. The good news is that March is drier at 2.6mm/day and air temperatures are starting to climb to 10.7°C, so the occasional sunny day with offshore SSE flow can produce surprisingly fun, groomed waves. It is a transition month - the ocean still has winter power, but you need to pick your windows more carefully.
