What is the best time of year to visit the American west?

The season runs from May to September. A few years ago, it was easy to answer this question. But for the last couple of years it hasn’t been that easy. May is still one of the best month for motorcycle riding. It rarely rains at this time of year, but there are still cool periods. Don’t forget that while the American west is very low in terms of latitude (Sahara), it is often very high in altitude, and you will be riding through 3,000-meter/10,000-foot passes. In June, the temperatures have become surprising. Notably, it is not uncommon to be confronted with high temperatures, especially at the end of the month. July and August are hot, but less so than in the past and thunderstorms occur regularly (July and especially August), cooling down the atmosphere. September should be good for most people. Hot, but not sweltering. The sun sets a bit earlier, however, and you have to be careful with your timing so as not to miss the superb sunsets at the big national parks! In a word, the U.S.A. is a country where weather incidents happen, and that will be part of your personal adventure. Since the year 2000, Monument Valley has become green again and the Mojave Desert is increasingly dry.
