Conditions at Keramas in March
March: Transition Begins, Windows Narrow
March is the shoulder month where the northwest monsoon loosens its grip. Ideal wind drops to 40%, and average swell height eases slightly to 2.5-3ft (0.8m), but the 13.3s period is still long and powerful. The swell direction becomes even more SSW-dominant (72.9%), with SW contributing 17.1% and WSW 6.4%; the S component begins to creep in at 2.6%. Most waves remain in the 2-3ft (0.5-1m) range, while 19.5% from the SSW/SW/WSW window reaches 3-5ft (1-1.5m).
The first signs of the SE trade-wind season appear: ESE, SE, SSE and S winds increase in frequency, bringing more onshore texture. Still, the W/WSW flow remains present, and 40% ideal days provide decent opportunities. Rainfall eases to 6.42mm/day, air temp averages 26.9°C (24.0-30.2°C), and water temp stays warm at 29.1°C.
