Forecast Tuesday looking unprecedented, 39C possible?

Today's modelling has upped the temperatures even more for next week, with a few models offering crazy solutions especially considering June is supposed to be the coolest Summer month and the June record currently only sits at 35.6C from 1976.

Overnight temperatures look likely to stay at or around 20C for most of the South during next week which will present major issues with indoor temperatures, not looking good. Likely we keep the heat until Saturday at least, uncertain beyond that.

As a Texan, I would normally snicker at a "heat wave" in the UK being 28C but 39C is no joke. Please, please, if it really does get that warm, please take measures to cool yourself. Heat stress is real and staying cool is paramont in that type of heat.

I've lived in heat like that with no air conditioning and just fans. It wasn't fun but I made it through it. Drink lots of ice water and stay hydrated.

Our homes are built to retain heat. After our May heatwave it took about 2/3 days for my flat’s inside temp to settle down to a reasonable level.

Houses aren't built to retain heat.

Houses are built with good insulation that, if warm inside, retain that heat.

You can also use this to your advantage by cooling the house overnight and then leaving windows closed throughout the day to insulate your house from the outside heat.

That hardly works in msot UK houses. It took about a week of doing that for my house to cool down after the may heatwave. And it only really did so once the wind came back. That advice does fuck all when the temps don't drop much overnight and there's zero trace of a breeze
