Conditions at Kapu Beach in July
July: Peak Monsoon, Maximum Mess
July is statistically the worst month for surf quality at Kapu, with ideal wind a tiny 4 percent. The swell, however, is huge: average height reaches 7-8ft (2.3m) and W dominates like a freight train at 59.1 percent of all wave energy, with WSW providing another 10 percent. There are large concentrations of 6.5-8ft (2-2.5m) waves, frequent 5-6.5ft (1.5-2m) waves, and enough over-8ft (2.5m+) wave energy to remind you who is boss.
But the surface conditions are brutal. Persistent W/WSW/WNW winds blow straight into a beach that faces WSW, creating raw, lumpy, closed-out conditions. The 10.4s period only adds to the relentless, heavy nature of the surf. With 33.8 mm/day of rain, low clouds, and water temps dropping slightly to 28.0°C, this is the true heart of the monsoon - an awe-inspiring, mostly unrideable ocean unless you find a rare protected sandbar.
