August is not the best time to be backpacking the Katy Trail unless you like sleeping naked on top of your pad, sweating and praying for a breeze. The end of August starts to see some cooling. Wait until October for the change of seasons and the wineries' October fests, or at least until mid-September for cooler and less humid weather.
