Conditions at Airport in March
March: A Clash of Monsoons
March is the great transition month. The northwest monsoon is losing ground while the southeast trades begin to assert themselves over southern Indonesia. Wind charts show a much more balanced picture: W/WNW/WSW still totals about 40%, but E/ESE/SE already combine for 28% and ENE adds another 6.3%. That lifts the ideal-wind score to 45%, the first meaningful jump of the year. Average swell height eases slightly to 5ft (1.6m), but the period lengthens to 13.3s, meaning the SSW groundswell is better organized and more powerful. The energy arrives predominantly from SSW (58.8%), with SW chipping in another 30.8% and a small WSW component of 4.9%.
Air temperature sits at 25.6°C, water at 29.3°C, and rainfall drops to 6.12mm/day. The combination of longer period and more offshore wind makes March significantly cleaner than the heart of the wet season. It is still a gamble, but when the trades win the battle, Airport is well overhead and rippable.
