It has been a warm winter, and for example, hit exactly 80 degrees today about 20 miles away. Getting into the mid-90s by the end of the month would be pretty rare, but it might be mid-80s and it might be mid-70s.
Your itinerary seems reasonable in terms of miles and campsite availability, and should give you a good tour of the southern Supes Wilderness.
It it gets really hot, and you can start early, head east to dripping springs, and head for Reavis Ranch the next day. You can camp at Reavis and explore Circlestone, then head back. Same parking area. Or if you have high clearance you could start from a trailhead further east. The eastern Supes are higher in elevation on average than the western sections and about 10-15 degrees cooler.
However, if you are comfortable with low 90s I think you'll be fine sticking to your plan A even if you are unlucky enough to arrive during a heat wave.

As for a Plan B, any suggestions? And any guidance on what counts as hot? I'm accustomed to hiking when it's in the high 80s/low 90s, but that's with high humidity and nearly total tree cover. I have no idea what would be too hot in the desert.
