Hi Guys: I'm just starting to plan a trip to Southern Utah for next year. Initially, I choose the month of September because the rainfall seemed about average and the temperatures are starting to cool down. One of my riding friends said not to go in September because it is the "monsoon" season. This monsoon season does not seem to be born out in the rainfall records. The NWS lists average historic rainfall amounts by month. In Utah, spring (March, April, and May) is the rainy season with over 2" of rain each month. Summer is dry and September averages 1.5 inches. I'm hoping that someone on the forum lives in Utah or has visited there enough to give me some good recommendations. Does this monsoon season exist? Does it occur each year or is it only an occasional occurrence like El Nino? Thanks!
