First Groyne is a beach break located on Sydney's northern beaches, facing northeast toward the Tasman Sea. The spot is defined by a groyne structure that extends into the water, creating a defined launch and recovery area. The beach is backed by dense residential development, limiting space and access windows. Average conditions are modest with 1.38m waves and 6.5-knot average wind, making this a suitable location for learning and progression rather than advanced riding. The spot experiences very low wind reliability at 5.8%, meaning consistent sessions are infrequent. Best conditions occur with northwesterly winds (around 315°), which approach side-shore relative to the northeast-facing coast. Water temperature averages 17.9°C, requiring a wetsuit year-round. The groyne provides some wave organization but also creates hazards including turbulent water, shallow zones, and structural obstacles. This spot suits beginners and early-intermediate kiters during rare favorable wind windows, though low frequency means it works best as a secondary option alongside more reliable locations. Access may be subject to beach restrictions given the residential context.
