We have touched on all the flat water spots near LW that I would suggest previously in this thread. Waves aren't so bad in fact that is what some of us ride for. Some unexpected side shore wind came up today to around 20 mph. As it was side shore the waves were around 2 to 3 ft., less earlier and not much of a barrier.
There are a wide variety of riding venues just in South Florida, wind willing, check them out! More at the top stickies at:
