if you have 10 minutes some time, take one of those on line dosha quizes on any ayurvedic website. this may provide more information for you regarding temperament, diet, weather, etc.
if you like the dry then you definitely are not a vata constitution, you may be either pitta or kapha or mix. pittas usually don't like too much heat. if you are a kapha constitution i can give you some good things to try like eating popcorn to dry out your excess water.
