Conditions at Coke's in May
May: Southwest Monsoon Bloom and the Bumpy Trade-Off
May is when the southwest monsoon takes hold. A broad monsoon trough stretches across the equatorial Indian Ocean, and strong westerly winds become the norm - W and WSW together account for nearly 68% of all wind observations. This is the flip side of Coke's season: enough Southern Ocean energy to raise average swell heights to 1.1m and keep periods at a rideable 7.5s, but with a lot of west in the mix. The swell distribution shows WSW at 22.9%, SW at 16.6% and W at 15.8%, while true SSE/S/SSW directions total roughly 39%. That means a substantial portion of energy is arriving from the wrong side of the compass or has to wrap and bend to reach the reef.
Ideal surfing wind drops to just 28%, the second-lowest of the year. Rain ramps up to 6.42mm per day, and the air stays a sticky 28.5°C with water at 29.9°C. The result is inconsistent quality: occasional pumping 3-4ft (0.9-1.2m) SSE/S/SSW pulses can be excellent, but they are often accompanied by westerly bumps. May is a bridge month - the swell is arriving, but the wind has not yet settled into a favorable rhythm.
