you can be lucky and have 9/9 days of solid wind like me. Pick your time well and have good luck. Wind stays longer than Margarita and is MUCH better than coche.
Stay as long as you can you won't regret it.
The most beautiful kitesurfing on the planet, off the back of yachts, kiting between islands, amazing food, beautiful accomodation (if you can afford it), warm turqoise water as far as the eye can see, flat water, constant winds, kiting with turtles, amazing beyond belief
but often spots need a rescue boat (hence better by staying on yachts - no more expensive than in gran roque) some spots are hard and expensive to get to without a yacht.
