Is it too damn hot for the lake?

I have friends coming into town for July 4th weekend, and we have been planning to rent a pontoon boat on Lake Conroe Saturday.

Real feel temperature for Saturday will be 109. I know being on the water will make things a little cooler, and of course we will swim some too.

But, be real with me, is it too damn hot for even the lake? I’d rather not be miserable.
