You will need a bigger kite for sure or you will only be able to ride in 20+ mph wind days and when the winds are 20+ they are usually gusting to 30+
so that is less then ideal to be learning to ride in.
At your weight you are going to want a 5m for moderate winds in the low to mid teens or a 10m depower.
Ideal riding conditions to learn on are 10-15ish.
High winds are tricky and low winds are just frustrating.
You've got a hundred pounds on me and I couldn't get going on a 2.5 or 3 until around 15 and I'd put them away around 25.
I may be going to Nahant tomorrow afternoon if I can coordinate a ride home for my son from soccer.
Sunday forecast looks crap. Tomorrow afternoon looks good but then dropping off (12 - 8mph).
You will not be powered at 12 or 8 mph but you may be able to work the 3 at around 12mph to get rolling down wind OK (but you won't get back upwind).
