When would you say it's too late to go? April still good? May? Obviously too hot in the summer, and no ducks, though I believe more shore birds.
There is usually a significant part of the waterfowl migration still around through March and this time of the year some interesting wading birds can show up. Over the years I have visited in every month and there is always something interesting but much depends on rainfall and water allocations.
