Maui is a great place to go during that time... and not just to kite.
Its low season. There's wind every day. Its warm. You need to be mobile to get to the waves but no problem.
I'll pm you a guy i know from which you can rent an oldie nissan for like $18/day. Don't stay in one place more than one night. Move around. The island is awesome and has tons to see and do. That's how we traveled there last year... not to mention we coincided with a dozen other local kiters there for a week.
Things to do.
Surf (i rented a board the whole time i was there vs bringing my own)
Hike (waterfalls forests natural pools beaches)
Luau (no need to pay $100+ per person, i made that mistake)
Kite every day (kite beach during the day, kihei in the afternoons)
Find blow holes (all over)
Zip Lines (hella fun!)
Hotels don't really get cheaper than $100/ni that's about the most expensive part of the trip for us. We drove the whole island. In 10 or so days just once we stayed in the same hotel. Even slept in a car one ni driving around the Hana side cuase its super long and we wanted to do some hikes the next morning. Lol on my birthday too. (not much to see in hana

)
