I havenāt read the other responses, but I thought Iād reply. I live in Central Texas and have trailered my horses several times in 100+ temperatures.
Now, I did buy a custom trailer designed with bad weather in mind, but I have to tell you that they were always just fine, much to my shock. I have four roof vents (two on each side) and lots of windows, and I opened everything up for maximum airflow. I also have fans in the trailer that I turned on. As long as youāre moving, you should be fine ā mine never even broke a sweat. Even if youāre stopping and a stoplight every now and then you will probably be OK.
A couple of things you might do:
- Leave the trailer windows all open (assuming you can) overnight, and in the morning park it where it will be in the shade all morning. At least youāll start off nice and cool in there.
- Hose and sweat scrape your horses before loading.
- Open all windows and keep them open.
I tried putting ice in the trailer and I couldnāt tell that it made any difference.
