Launching and rigging areas are excellent. The tide goes out a little way when low and in easterlies the beach develops a decent wind swell. It is a popular spot in easterlies as it's pretty gentle but a lot of fun. In northerly winds it offers good slalom conditions. It's a great spot to access some of the Hauraki Gulf islands like Motuihe, Waiheke and Browns.
Southerlies produce pretty flat water conditions but are offshore.
The list could go on for ever. Variety is the spice of life and Auckland's windsurfing spots definitely offer this.
