The main part of Anakoha Bay acts a wind tunnel but Te Puru Bay on the western side is sheltered from winds in all but strong N to SE conditions. The bay has a depth of about six meters giving good holding in mud, without the need for effort with large quantities of anchor cable. In strong NW to N conditions a roll that can be most uncomfortable is pushed in to the bay. In moderate W to N winds the best shelter is near the moorings on the north-western side of the bay. In SE to WSN conditions the best shelter is in the cove on the southern shore where it is possible to get a stern line ashore. Generally a stern line is unnecessary as there is plenty of room to swing an anchor.
This Te Puru Bay can become very dangerous in heavy NW to N swell.
