One has to stop about every 50 miles to pee anyway, so there's no reason to carry more water than 50 mile's worth. The hottest pass climbs I've done were 105° at the bottom.
I regularly do century rides without peeing (although not guaranteed!). I did one at the weekend. It was fairly hot and I got through 2L of water/energy/electrolyte mix. I was a little short actually, could have done with another 0.5L, but wasn't critical. I ran out with about 15 km to go. This was a hard tempo ride at just under 5 hours.
