Sea very rough with occasional strong longshore drift across entrance where waves are entering very wide & moving up the channel into the estuary where they turn sharply to east. Salt (green water) for about 40 - 50m. WSW/SW swell sending waves far up on beach - water is then travelling down a slight depression west along beach behind beach face. Swell waves are curving around at actual entrance. Sand visible in breakers far out to sea & a very large amount of seaweed has been deposited in area where channel meets estuary & along the SW area of exposed sand
