Conditions at Keramas in June
June: Firing Southern Swell, Blown-Out Surface
June is a classic winter-consistency month for the Indian Ocean at Keramas, but the local wind is uncooperative. Average swell height reaches about 3-4ft (1.1m), and the average period is a strong 14.2s. The swell mix is SSW (46.4%) and S (42.1%), with SSE at 10.4%-a broad, powerful south quadrant. Roughly 27.4% of the SSW energy falls in the 3-5ft (1-1.5m) class, and 2.1% hits 5-6ft (1.5-2m); the S direction adds another 21.9% at 3-5ft. There is plenty of groundswell moving through.
However, ideal wind is only 4%. ESE (36.0%) and SE (39.1%) trade winds dominate, with some 20-30kph gusts appearing. The combination creates persistent onshore texture, turning an otherwise high-performance reef into a bumpy, difficult wave. Dry and cool: 1.43mm/day rain, 25.9°C air, 28.0°C water.
