Can also support Cooktown as the windiest spot, unless you have boat connections or $$ and can get to Lizard Island. I looked at the wind roses mentioned in the previous post and can't see a better dry season figure. Torres Straight also very windy.
Out of 5 weeks at Lizard last winter, we had maybe 5 days too light to kite, 5 days on 11m, 20 days on 8m in 20-30kn, and 5 days of 35-40kn too strong to kite on the 8m.
