Notes
Observations made around high tide
Natural opening occurred late pm. or overnight 13-05-18 resulting in a strong dark discharge out across a wide entrance proceeding in both an easterly & westerly direction. Strong longshore drift constantly crossing over outflow & meeting incoming a curved SW swell. Intermittent small waves going down channel into estuary. Sea is moderate but high waves are breaking on sand bar close to shore. Large amount of sand carried in backwash & out to sea
Beach has been strongly scoured by recent southerly strong gale to storm force winds creating a small dune in front of existing formation & covering large areas on dunes with deep sand. SW swell continues to impact the east end & a high long sand spit now extends out to sea at middle of beach. Beach is highest just close to entrance
