Hi Lynnwilby,

North America is wonderful - I've been several times and have thoroughly enjoyed it every time.

The one thing about the weather is that it is extremely unpredictable and you're travelling through a number of states which all have their own climates. But, to give you a bit of a guide, historically May, June and September has experiences warmer weather. In Las Vegas you may experience daytime highs of up to about 37 degrees (June),  in Jackson 23 degrees and Denver 28 degrees. However, it can get much cooler in the evenings.  Now, October is Autumn and MUCH cooler with highs in Las Vegas as 27 degrees (so still warmer than here in the UK) 19 degrees in Denver and 14 degrees in Jackson. Again, it is a lot cooler in the evenings.

Not sure if this helps with your decision or not.

Kindest regards,

Julia
