Every western river run I have been on has had upstream winds at some point in the afternoon.
I do not think there is a good answer as to exact times wind will start on any run.
My take is as soon as the sun warms up the area enough, upstream winds start. So the answer depends on the sun and clouds etc more than anything else
Which means the earlier you start to float the better chance for missing more of the upstream winds.
That ruby horse thief stretch especially if you launch from the state park is known for it's afternoon upstream wind before you get to the most popular camp spots.
The only time my group has missed the vicious upstream wind there, is when we camped at the State Park, rigged the boats with every thing but sleeping bags and pads, got up before day light, got a quick breakfast at the nearby McDonalds and were rowing just as the sun started to come up. That day the lunch crew made sandwiches in their raft and passed them out to the rest of the group so we did not waste time on shore. We were in camp, setting under a shade cotton wood tree enjoying early cocktails with a great afternoon cooling breeze!
