New York has awesome kiting spots with strong wind from september to June. We probably got 5 25 knots session during the summer as well, though usually we get 12 to 18 knots in summer.
Last winter was pretty mild so kited all the way to mid January, went to carribean for 2 weeks and kited again from mid februrary... Previous winter we stopped on January 1st, did a few snow kite session and started kiting again last week of february.
If you don't mind wearing a wetsuit you will have more fun in New York than light wind session in Miami.
I live on longisland but work downtown manhatthan. I have great spots 25 to 40 min away from home. From the city if I take train at 5:10 I can be at a spot at 6:30 for after work session. Or dawn session and still be at work around 10 am.
I usually can do 2 session a week. It was kiteable from saturday to Wednesday. did 3 session.
New Jersey has a lot of great spots too. Longisland has Ocean south, longisland Sound on the North with some nice offshore/bay setup. In the middle there is Great South bay with grassy island which can compare to outerbanks setup but with gustier wind. There are 4 different shore you can kite from, so tons of possibility.
