we're kind of lucky here in brissy,
although we don't get the consistency of FNQ in winter or WA in summer,
we are right in the middle (latitude) of the seasonal changes between the northern wet season in summer and the southern wet season in winter.
sure sometimes we might go a couple of weeks between decent blows and it doesn't get as strong as other places, but we all sail all year round here and just adjust our location depending on wind direction.
we don't really have a season where we say there is no wind except potentially mid to end autumn, just a month really, (may) every other time is up for grabs.
eg,
august to nov - Northerlies
nov to jan - Nor Easterlies
dec to march/april - Sou Easterlies
jun-august - Westerlies
yearly wind rose.
