I have an opportunity to go to St. George in either the beginning of August or November? What is the weather like in both of these months? I wanted to see Zion Park and also get some golf in. Will it be too hot in August for both of these activities? I could also choose the area around Bryce if the weather would be better in either of these months. Please help me to make a decision. Although I have been to SLC many times, I have never been farther south in Utah. I hear it is absolutely beautiful. Thanks!
