March: Pre-Monsoon Swell Builds, Wind Turns Tricky
March is the first real transition month at Kapu. The average swell height remains at a modest 2-3ft (0.8m), but the direction spread becomes more balanced - WSW accounts for 21.9 percent, W for 21.6, WNW for 23.2 and SW for 15.6. That is a sign of the approaching southwest monsoon, with more southerly component than the dead-of-winter NW swells. Periods still average a serviceable 9.5s, and a handful of 3-5ft (1-1.5m) waves appear from WNW and NW.
The trade-off is wind. Ideal offshore conditions drop to 30 percent, and the wind rose shows strengthening WNW/W/NNW components. The mornings can still be glassy, but the afternoon sea breeze increasingly puts a crumble on the face. With rain still scarce at 0.45 mm/day and water temperatures at 29.7°C, it is warm, but you will need to pick your session carefully.
