The first thing you can do is to get out on the water even when the wind is light. Dust the cobwebs off that old long board or buy a cheap one from somewhere, better yet buy a windSUP. Having a board that you can use in light winds will open up a whole new side to windsurfing; there’s a lot you can do when the wind is not there. For example:

Try your hand at light wind freestyle. It’s only been relatively recently that freestyle has moved into the planing side of our sport, before freestyle was all about non planing tricks. Go out with some friends, do some sail spinning or practice your tacks. This will not only be fun, but you will also learn so much more rig control, which will ultimately help you when the wind gets stronger.
