I'm a beginner who just got back from Buen Hombre. Great experience, I learned a lot and had a lot of room to learn it. The wind gets going to a good point for kiting around 11AM/1PM and gets its strongest starting around 5PM. Evening conditions are ideal for kiting during the full moon. The kite school has a great instructor, Mikey, if you're looking for lessons. They also rent all kinds of equipment, including water shoes - necessary for kiting on the semi-reef bay. The school are all English-speaking, and if you call ahead they can help arrange transportation. The food at any of the beach restaurants is excellent. This is not a tourist community, so if you're planning to stay for a longer vacation it helps to have some Spanish - but isn't necessary if you're staying at the school. There is no garbage service so it's kind to make an effort to minimize the garbage you're leaving behind.
Gusts went up to about 26/27 knots, but I also happened to be there for a rare depression so there were two days of rain and little wind to recover from. Biggest kite I used during the week was an 11m, smallest an 8m. I'd recommend either coming in for the day when you see that the wind is up, or staying for a week or two. If you're staying longer, bring reading material in case you get a down day. Once the wind is up it's going until well past dark.
