Spring, Summer and into Autumn is the best time for winds in SEQ - you should get prevailing SE or NE (cross-onshore) winds reasonably consistently. I use an 11m2 or 7m2 for the surf, which covers most conditions. July/ August (Winter) we can get periods of offshore Easterly winds, so not recommended. Can be very hot and wet over the Xmas/ January period though. Hopefully we'll start to get some decent winds soon, as there's been nothing for quite a while now!!
