hey davebryer
anything from 7 - 12m hard to tell
city seabreezes can be quite good from 15 - 28 knots, down south for waves its light seabreezes but we rly on patterns and they can be light to strong wind.
I use a 6 and 9m most bigger guys have 8-11m as quiver
check saksa (ksa) web page for local spots also
