Summer months are pretty hot, especially at the bottom of the canyon, where it can be well over a hundred. The best hiking weather is generally April and May, and late September through October. But then, these are the hardest times to get backcountry permits. You would send your applicAtion on May 1 for a permit date any time in September.
You can do the Grand Canyon in one day if you just want to look at it. Hiking down into it and/or rafting it takes much longer but is certainly well worth it. At both Bryce and Zion there is easily enough to keep you busy there for 2-3 days. You can't really do a hike or two before noon at either place.
