Notes
AHD G6 2.30 @ 09;37 Air pressure 1010 SW swell 14-19-18 secs
Pale discharge only around the mouth, large amount of sand in breakers. At 10:40 waves/saltwater was entering up channel. Waves & green water on eastside of channel & very narrow flow of slightly darker water moving downstream against cliff towards mouth assisted by extremely strong north wind
Very strong 5-6 NNW wind driving waves to SE side of estuary, but stronger northerly gusts were blowing sand down the channel into the sea, wind is also causing waves to impact against high area of sand mid south side of estuary. Despite this waves coming down the channel reach the estuary & disappear only to reappear much further north as they meet the sand bar
Only 2 photos taken because of wind strength
