Hi-I'm planning my first trip to Guatemala and expect to spend most of my time in/around the Panajachel/Atitlan area. I realize that this is a tropical climate but I'm definitely NOT a hot-weather person and high humidity just does me in. I've read some about the rainy/dry season and the climate in general but would appreciate input on what to expect, weather-wise. Specifically: when would be the best time to go and what are typical temps/humidity levels like at those times? Thanks for any tips you can share.
