Conditions at Yin Yang in April
April: Clean Westerly Flow, South Swell Arrives
April marks the real onset of the southwest monsoon wind regime. The wind is ideal for surfing 63% of the time, with W (24.4%), WSW (18.8%) and WNW (16.7%) dominating the rose. That means offshore, groomed surfaces at Yin Yang for the first time in months. Swell direction, however, has shifted away from the classic E/SE angles: SSE contributes 34.5%, S 25.5%, SSW 16.2% and SW 9.4%. Average wave height is 1.0m (3.3ft) with a 7.0s period, so the waves are clean but not big. This is the start of the best quality-over-quantity run of the year, when the reefs turn glassy and the S/SSW groundswell begins to wrap into the east-facing sides of the atoll.
