Heat is much harder to deal with than the cold. Like others mentioned, you have to learn to tolerate it as you really cant get used to it or change the fact that it will get hot in the summer. I cant give much advice here as our weather is always good in northern New England. We have those occasional days of upper 80s and high humidity but for the most part, every morning commute is never above the 60s. The afternoon commute can be warm but nothing like what you guys have to put up with in the south. Not anxious for snow and cold yet though.
