Hi,
I tend to water late in the day, as the Sun is going down. This gives the water time to reach the roots? and the plants time to take it up, but it may not work that way.

I believe that it is high night time temperatures that cause cacti to shut down, not high day time temperatures, so it wouldn't make any difference what time of day you water your plants. The optimum growing conditions are high day time temperatures and low night time temperatures. Happy to be corrected though.
There is a Woody Minnich instructional video on YT, where he discusses some of these points, among other stuff, well worth a look. https://www.youtube.com/watch?v=K0SYqY4_xLs.
Lots of my plants are in small pots or cells, in very porous mix, so I can literally water many plants daily when its hot.
I didn't record temperatures in the GH over the last few days but it wasn't massively sunny in Birmingham, so I'm sure it as been hotter on very sunny calm days before.
I've noticed a couple of plants with a little bit of scorch today, but nothing serious, including small seedlings which seem OK.
I gave mine a soak yesterday evening when the temperatures were definitely on their way back down to normal.
Thankfully, I don't think anything has been damaged and/or lost. It may be my imagination but my jatropha podagrica was looking a bit unhappy. That just came inside for a couple of days and is now back in the conservatory.
Growing in Nottingham for the past 4 years and recently found my way to a Nottingham branch meeting. A few plants on a windowsill has very quickly turned into a greenhouse full!
Attempting to grow a range of turbinicarpus, coryphantha, escobaria and several other cactus genera. Tylecodons, pelargoniums and conophytums keep me occupied in the winter and an ever expanding number of gasteria live under the bench.

I watered mine last night.
Inevitably, like washing the car, it is going to rain and be cloudy for the next two weeks!
The only damage I can see (so far) is one slightly pale Echinofossulocactus. The thin ribs have frazzled a bit.
Yesterday my 3 water butts were empty.
Overnight 2 are nearly refilled.
I suspect I know who/ where/why
Endeavouring to grow Aylostera, Echinocereus, Echinopsis, Gymnocalycium, Matucana, Rebutia, and Sulcorebutia. Fallen out of love with Lithops and aggravated by Aeoniums.
Currently being wooed by Haworthia, attempting hybridisation, and enticed by Mesembs.
I watered everything this morning except the higher altitude plants. In previous summers I have had taproot loss on Sulcorebutia and Eriosyce which I put down to being overgenerous with water in hot weather. These were last watered in late June and will stay dry now until I am convinced of cooler nights.

I've got some water now, but not much sun in the forecast until the middle of next week. More or less everything was watered shortly before the heatwave, but plenty of very dry pots already, so I'll be watering lots of things again in the next few days. Might even put some of them out in the rain, some cacti look very nice with wet spines.
