Tavel in Southwest USA in summer time

In general between the end of June and the end of Aug elevation determines the average day time temp. If you are under 5000ft it will be over 100 in the daytime, which will last until 2200-2300, 5000-6000 and it will be in the 90's, 6000-7000 and 80's will prevail. Keep in mind that the nigh time temps will drop by 20-30 degrees. The early mornings are the best time to be active.

IMPORTANT: If you are away from civilization have 1 gallon of water per person with you.

Back in 2007 we spent a couple weeks going to Zion, Coral Pink, Bryce and the Paiute trail. Loved it! I rode at Sand Hallow outside of Zion with a guide, then down to Coral Pink Sand Dunes, then a few days at Bryce walking the tourist areas and riding in the back county (best part of the trip) and then up to ride the Paiute trail. Mixed weather up there, had rain but never got really hot and that was around the 4th of July Holiday time frame.

I loved riding at Bryce and Coral Pink was amazing. But CP was hot like 118° the day we arrived, had to ride in the AM & PM, during the day we hung out with the generator running to keep cool.

You need to know how wide your SxS is as some trails will only allow 50" or less they enforce this by gates so you can't fudge.

If you go, grab the map at the ATV Utah Website it also has some good info.

Best ways to escape the heat are to go to higher elevation or to the coast.

Check out Cinder Hills OHV area in Flagstaff, right near Bonito USFS Campground at the entrance to Sunset Crater Nat'l Monument.

Colorado has a lot of scenic high elevation places. I don't know about ATVing there.

You bet, southern Utah is exceptional for ATV'ing and camping during those months. They also get the monsoon up there which can help cool it down in afternoon. We're planning 8 weeks from June through July there this year. Bryce, Zion etc are great.

There are plenty of mountains and high country to camp.

Traveled I 10 a couple of years ago.
Spent the night at the California/Arizona state line.
110 degrees in shade, 105 in rv.
Then, turned on a/c.
We're not doing that again....

It's dang hot in the SW states! Flagstaff and some other areas are the exception. I'd just make sure you have plugins and run the A/C or run a genny - it will be hot but make the trip anyway!

In our opinion it is too hot, but that's us. We will always plan to be in northern states at that time, but above 90 is too hot too us. If 100's plus is your thing, come on down!

West Texas, New Mexico, Arizona and the southern most quarter of So. California from July to September can be done but stay high...Flagstaff, Santa Fe etc. It's a dry heat...mostly...if that makes a difference to you.
