Hi Keith
Have a look at this webpage (
Henties Bay Tides), we arrive there on the 28 Feb, this more or less correlate to our experience, best fishing was on the falling tide in the evenings, wasn't much happening between over the weekend of the 6/7 March, also have a look at this thread (
Henties Bay Trip), these guys will post a detailed report when they are back, feel free to contact Chris or Sardyntjie, they will gladly assist you.
Good Luck
