Great idea, and worth doing,. We had a new shower installed earlier this year and debunked to a local hotel for a couple of days while the work was done. Why not?

Genuinely why wouldn’t you consider the option? If you have the time to be with him, he’ll be comfortable, you can bring him food into the hotel room

It's what I did with myself on that 40C day in 2022. Cost me £80 as a last-minute booking but it was worth every penny - watching the rush-hour traffic along the A2 from a large window, with the aircon set to 19C. And no commute the following morning, either, as work was just a couple of hundred yards down the road!

EDIT: I appreciate though this won't work for everyone, or even most people. Dev's situation is much more complicated than mine was!

Because we live in the middle of nowhere so I wouldn't know where to start as the nearest such hotel could be Exeter (which will be roasting). Because he wouldn't know what is happening, which would (if anything) make it worse. Because we have a mad dog who is important to dad but has no idea about urban life. Because we live in upland Devon and shouldn't have to think about fleeing the heat.

It's really difficult. There will be god knows how many people struggling like me this week.

30c, 31c, 35c, 38c, 37c, 31c, 29c, 28c, 

Buy an aircon unit? Stays in his happy place 

This is the most likely option. Any left 🤔

When I look at the GFS ensembles, I keep thinking large drop (it is) but in reality the scale make its look like it’s going to turn cold, but in reality we will still be above average but more moderate temps.

Yes pretty mad to think even a 10c drop in temperature we'd still be in heatwave conditions. 

A few places are now showing 40C on Wednesday on the auto output. 

BTW I was just looking back at my saved screenshots. On Sunday 17 July the UKV actually went for 43C max on the Tuesday so it was a bit over the top! The Met auto output on the Saturday had 42C in Lincolnshire. It had the right area for the peak of the heat though. 

Yes - it's a tricky one that, Dev. I wonder if one can hire an air con unit. Googling AI....

"Hiring a portable aircon unit for a few days in the UK typically costs between £60 to £100 per week, depending on the BTU capacity required. Several national tool and equipment hire companies offer short-term rentals and provide convenient click-and-collect, delivery, or in-store pickup options."

But with more of an easterly component to the drift the heat will be pushed westwards. Cheltenham once held the all time record with 37.1C in August 1990.

It's going to be hot , but think Arpege is over doing it. My bet would be 38c ish in places like Yeovil and Pershore. 

They are utter cack - just a fan with added humidity. They might knock a degree or so off on a very hot, very low humidity day but they're generally useless in the UK and shouldn't be marketed as they are. (I had one back in 2003, all that happened was the humidity went up and black mould grew in the filters... lovely.)

A proper portable a/c is the way to go if you want spot cooling.

We bought a portable A/C unit about 5 years back at a cost of about £150.

It felt like a luxury then but we've used it every summer since and it's been worth every penny. 

That one in the link won't help anyone, it's one of the dodgiest ads-as-content I've ever seen. It looks like the sort of thing you see on YouTube ads. They could have at least pretended it was legit by adding links to the other evap coolers/portable a/c units, and 99%? That's just OTT!

Some of these runs suggest the worst day (probably Thursday) could be something like

40C max/ 25C min

in a worst case scenario

These temperatures are a problem for people without aircon and unlike 2022 we have very high temps (albeit far less bad than that) sustained for days on end.

Yeah, because it's a cheap one and won't work.

You get what you pay for.

I think some of the "it's just summer" crowd are likely to get caught out - although I also expect red warnings and, once those are issued, some schools to close etc.

Having lugged laptops across a playground in 40C in July 2022 - it's not an experience I ever want to repeat. Every breath burned, and that was frankly scary to experience.
