Conditions at Waikiki Beach in March
March: Trade Swell Reclaims the Driver Seat
March is a shoulder month. The average swell height drops slightly to 5-6ft (1.7m) and the period to 11.8 seconds. The NW/NNW/WNW swell still contributes a respectable 25%, with NW at 9.8%, NNW 8.4%, and WNW 6.8%, but the balance has shifted toward the trades. ENE swell jumps to 20.1%, E to 10.0%, and NE to 10.8%. This mix means the spot sees a blend of leftover North Pacific groundswell and more locally generated trade swell, often with inconsistent intervals between swell trains.
The wind pattern shifts hard toward ENE: 45.2% of all observations are from the ENE, with NE adding 14.1% and E another 12.3%. Ideal offshore conditions drop to just 16%. Stronger 20-40kph ENE flow becomes common, so clean days are limited to periods when the trades relax and a S/SSW/SW flow develops. Air temperatures are steady at 22.8°C and water 24.2°C, while precipitation averages 2.39mm/day, making March one of the wetter transition months.
