Conditions at Kapu Beach in May
May: The Monsoon Breathes Down Your Neck
May is when the southwest monsoon starts knocking on the door at Kapu. Average swell height climbs to 3-4ft (1.1m) and the swell window swings strongly into the WSW: that direction pumps in 33.3 percent of the total, followed by SW at 24.6 and W at 20.8. Larger waves are on the increase, with 5-6.5ft (1.5-2m) heights appearing regularly and the first 6.5-8ft (2-2.5m) pulses showing up in the WSW/W bands. The 10.4s average period means there is decent power behind them.
Yet the wind is turning against the surfer. Ideal offshore wind drops to just 16 percent, while the prevailing flow out of the NW/WNW - cross-shore and onshore for this west-southwest facing beach - strengthens. Rain increases sharply to 5.42 mm/day and water temps hover near 30.5°C. Expect lumpy, wind-affected conditions except for occasional early morning windows before the sea breeze kicks in.
