Weather in August in LT
My wife and I were there for 9 days in mid August 2008 and the weather was hot and a little humid, but not at all unpleasant. It rained as I recall on 2 different afternoons for several hours. August is not really the heart of huricane season if you were wondering. In the hotel (Alesei) we used the fans more than the AC. In short, I don't think the weather will be an issue.
