Gangkou is a sheltered bay spot located in southern China's coastal region, characterized by a semi-enclosed water body with moderate residential and industrial development along the shoreline. The bay faces southeast, with the coast running roughly northeast-southwest. This configuration provides natural wind funnel effects and wave dampening, making it suitable for lighter wind conditions. The spot receives minimal swell due to bay protection, with average wave heights around 0.8m. Best conditions occur with northeast winds (approximately 45°), which align side-shore to the beach break. The very low wind reliability (2.6%) and average wind speed of 5.5 knots indicate this is a marginal wind spot that works only during specific seasonal patterns or strong weather systems. Visible industrial facilities and boat traffic suggest moderate congestion. The shallow, calm waters and protected bay make this suitable for beginner to intermediate kiters seeking light-wind practice, though sessions will be infrequent. Water quality considerations should be noted given industrial proximity.
