I'm from florida, and in July I leave because there is no wind, I goto the Gorge with 25 kts everyday. Florida has zero unless a hurricane comes
The closest place to kite from louisiana is probably Texas ( galveston ) usually a 15 kts seabreeze 75% during summer, but not as windy as the gorge.
California, around sherman island or san francisco is also windy during summer everyday in the afternoons
