? about weather at Grand Canyon

Our favorite time to go to south rim of GC is September. We have been there numerous times and have only experienced near perfect weather. I don't think we ever had to use air cond. The most extreme weather we experienced was a rain shower as we were finishing our hike up Bright Angel....very welcome. We did see an amazing electrical storm but it was in the distance.The crowds are lighter in Sept ....the shuttle buses are efficient-they drop you off at one overlook and when you are done oohing and ahhing and taking pictures you just wait for the next shuttle to pick you up and take you on to the next overlook. Don't think we ever waited more than 10 mins that timemof year.We are going back in Sept,too, but staying at Maswik Lodge this time instead of taking the 5er.
One last thing....you are safe wearing hiking shorts but carry light jacket for early morn. If you want to see a sunrise I suggest you wear long pants,warm jacket. It can get really cold that early in morning. I learned the hard way. Have fun!!!

Thanks everyone for all the great information. We so appreciate it! Thanks again :)

Sept 8th averages are 74 and 43.

I use http://www.wunderground.com for all my planning. Information overload! But you can click on almanac and put in any date for historical data. Great website.

It can get pretty warm in early September even at 8000’, in the high 70’s and low 80’s. But it cools off nice in the evening. Having a site in the shade would help a lot. It’s hard to tell what the temps might be when you’re there; even the weathermen seem to be guessing. I suspect you won’t know if you will need HU’s until you get there.

Was there a few years ago and stayed at the williams koa as the sites up at the south rim were booked already. Anyway, in mid july the day temps were in the 80's and we needed the ac but the nites dropped way back to 45 and needed the heat. Crazy but remember you are at a 8000 ft elevation and they can get snow at anytime.

Thanks akrv! nice, very appreciated :)
