When the dews go up there is more moisture in the air and if you don't add enough products with ingredients that make sure the hair have enough moisture it will try to steal some from the air => More frizz. Do you use a conditioner as leave in?

Regarding curl type, it is really hard to say until you've taken good care of your hair for a while and have learned how to style it. I only have real damage at my ends, which still is i n fairly good condition, but six months in my hair keeps on changing and the hair growing out since I started is in a very different condition to the rest. Also, the seasons will affect your curls as well.
