Rough sea creating backwash & longshore drift across entrance over weak outflow -some small waves entering channel & travelling up into estuary. Waves in all directions at entrance.

High sand at mid beach now extending further out to sea two distinct bays are starting to form along beach. Sand slopes down to entrance

Very large no. small fish in shallows along E side of estuary
