Lots of water for both. Shade for the beast. Light-weight, long-sleeved shirts for the humans and a broad-brimmed hat to keep the sun off.
When we lived in Arabia, we didn't try to ride in the heat of the day. Pretty much from 7 am to 4 pm was brutal in the summer. The road and landscape workers could be seen in the hottest part of the day still working, completely covered head to toe with work overalls and gutra (head covering) wrapped securely around their entire head and face. Believe it or not, they stayed cooler than way than they could have in shorts and tees. Same concept around here with ranchers and their long-sleeved work shirts and fugly sombrero-esque hats.

Too hot here for too long ~ seriously ~ high high and humidity ~ hosing ALL and they are doing "not much" just some turn out time in pastures or round pens in the woods and then showers and back inside to the Wind Tunnel = Many, Many Fans ~ individual stall fans & ceiling fans & aisle drum fans ~ electric bill should be just as serious ~ OH ! and water bill too ! Just trying to survive ~
I feel your pain. I have two oldsters and we had high temps and humidty for couple of weeks straight. Didn't attempt any activity except the ones that cooled everyone off. Hosing off (4 times the day it was 115* heat index), and fans like said above. Try to keep the water cool to get them to drink more.
We have dipped down into the 70's this past weekend with rain - It was wonderful!!! Heat expected back tomrrow .
Weather guy said nature tries to balance things out so when extremely hot soon will be lower then normal temps. Judging from this past year he seems right - extreme winter w/ more snow then we've ever had, and hot-hot-hot summer!
We're also having high heat...my air conditioner has been running 24/7 which is very unusual. I am not looking forward to my electric bill. We've been 110+ for weeks, and relatively high humidity for our desert.
As far as the horses go, I find the youngsters in decent condition are okay, but the old ones or horses in poor condition (especially overweight) struggle. Well-ventilated sheds, fans, and not working in the heat of the day are your friend. I'll also occasionally soak a good fly sheet and put it on a horse. It seems to work better than simply wetting the horse.
We're having the same weather and my OTTB colic-ed last Thursday from dehydration-despite ample water being available 24/7.
I think I have now convinced the barn to dump and refill troughs and buckets. When I temped the turnout troughs at 6pm (when they go out right now) it was 92 degrees on Friday.
One way we found to give horses an incentive to drink more is to let them meander around several pens and tanks, so they will drink a little here, there and over yonder.
This way, they do end up drinking more than from just one tank.
Wow DDTM, that would be awful for a horse! It is 100 here today and I had a 4:00 vet appt w/ one horse. I left the trailer parked in the barn to keep it cool, then hosed off the mare just before I loaded her up. Drove 70 mph and she arrived in good shape.
I did find some nice charts of actual inside surface readings that show a difference of 30 degrees between mill finish and white insulated roof. These readings were taking in May in Colorado where the average high is 70 degree. Can you imagine the difference at 100 degrees.
