I take it you are heading to the Southern end, if so it's all about the tides and currents.
If the wind is SE on incoming tide do Woorim, Out going do Passage or Red beach. Pebble beach is also good in a SE and is not current dependant but needs at least half tide or more for water. Launching is around trees as well so be safe.
If wind is NE then head to Woorim on a outgoing tide, not much doing on a incoming tide.
For epic days a big S to SE wind on a outgoing tide is the way to go on the passage up where the wreck use to be, head out the the outer sand banks off Godwin beach for mega jumps. Remember get in trouble in the current and you will need help or a new kite as the need to get back to the beach is urgent as the current will take you far in a sort time.
A sharp coffee rock ledge runs along the beach on the passage side and close to low tide is impossible to see so keep an eye for that.
Only kite the passage and Woorim if you are experienced if not head to pebble beach but be careful with the trees and razer shells under the sand.
Not many people like the southern end due to the tides and current but if you read the conditions and hook up with locals who can show you then it's a lot of fun.

thanks for that hardcarve, i will get myself a tide chart. had no idea it was so tide dependent there
