Notes

Observations made close to high tide. Mouth barred after gale force south winds & high seas on 11-05-2018. Berm is very low at entrance as 3 rocks are well exposed but rises high about mid channel & extends north under shallow water well into estuary. Wind & waves have scoured out east end of beach which is now lowest part. The highest part occurs just east of the entrance which is wide with some longshore drift visible

Wind has reshaped the dunes depositing large amounts of sand over vegetation and removing it from other areas. Rock falls have increased on south & east sides of Pt. Ronald
