Conditions at Kapu Beach in August
August: Big Swell Begins to Ebb, Wind Still Dominant
August remains firmly in the southwest monsoon pattern, though there are small signs of easing. Average swell height is still a solid 6ft (1.9m), and the swell window is again monopolized by W at 61.4 percent and WSW at 28.8 percent. Most of the wave energy sits in the 5-6.5ft (1.5-2m) and 6.5-8ft (2-2.5m) classes, with only a tiny percentage of XXL waves above 8ft (2.5m+). Periods average 9.8s, so it is a little more disorganized than the peak monsoon months.
Ideal wind is only 7 percent, with the wind rose still loaded with WNW, W, WSW and NW flow. The beach will be frequently blown-out, rainy at 23.59 mm/day, and rough. Water temperatures fall to 27.3°C, but the main issue is not cold - it is the relentless onshore monsoon energy. For the patient surfer, the best windows are likely to come in the brief lulls between squalls.
