Conditions at Vairao in March

March: Long Periods and Brighter, Cleaner Windows

March is a transition month in the best sense. Average surf size holds at 6ft (1.9m), but the period increases to 12.6s, giving every swell that hits the reef a bit more push. Direction-wise the S and SSE quadrants dominate heavily-S is 31% and SSE is 25.3%-so the swell still has a distinctly southerly character. The good news is that the wind becomes more cooperative, with ideal offshore conditions 41% of the time as E, ESE and ENE flows pipe across the exposed bay.

While the percentage of true SW-WNW swell drops to around 8%, the quality of the windows that do open up is high. The dry season is approaching, rainfall falls to 4.84mm/day, water temperature peaks at 28.9°C, and the average air temp of 27.3°C keeps it feeling tropical. If you time the SW pulses right, March can deliver long-period, hollow, rippable waves with a light offshore sheen-arguably some of the cleanest surf of the year at Vairao.
