My advise: leverage your expectations
Feb and Jun are the worst months when it comes to wind at the islands. But then the elements don't know the calendar, they are the calendar.
I don't know what board you ride, what size you are, what your skill level is. So the best I can say for now is that your bring a kite size your are comfortable with on your home turf. If you get lucky you may get something around 20ish (with gusts). The rest is hit or miss. With one kite you may get one or two days of kiting, with a second kite perhaps you are looking at three days. All depends if it is worth it packing two kites. So best is, that you keep your days flexible, ready to roll if the wind picks up. Otherwise here is so much other fun stuff to do.
