@Remittancegirl @radioclash @svenscholz Must say this is viscerally scary.

@radioclash @Remittancegirl @svenscholz what kind of "experience" you mean? "LoL" vs data?

UK has literally 20GW of installed solar capacity which produced some 6.5% of total electricty in 2025. Sure, it works better in more sunny places, still not "LoL".

@radioclash @Remittancegirl @svenscholz solar is like 30% of UK's energy generation on sunny days, so not exactly "lol"

@radioclash @Remittancegirl @svenscholz but we absolutely do.

Italian, Spanish, or Greek cities are all humming with AC in the summer.

Even for Poland, having a balcony was a major point in choosing my current apartment, so that I could install an AC unit there without hassle, even though I try not to use it unless I really feel like I have to.

AC power consumption is one of a really few things that synergizes well with solar panel output, especially in the north.

@Secret_Squirrel @Remittancegirl @svenscholz my experience comes mostly from (north) California, Florida, and Louisiana, so I don't know.

They all look more like a lazy construction work than anything (mounting a non-split unit on the top of the window is harder than just ripping a hole under said window and putting the thing on the floor).

@Remittancegirl @svenscholz um, well, they do have this vibe of a country that knows everything better than anyone else, don’t they.

@Remittancegirl @svenscholz Which makes me really wonder why on Earth the floor-mounted internal AC units are so popular in the US.

@Remittancegirl @svenscholz yep, that makes sense. Some top-mounted AC units have this mode of pushing the air horizontally all over the ceiling, which then somewhat uniformly falls down and mixes well, and the effect is much better than just blowing it down (with the same unit).

@Remittancegirl @svenscholz oh, that's interesting - I would have thought it's the opposite.

@Remittancegirl @svenscholz yeah, that's extreme.

BTW, do fans still help at those temperatures and humidities?

I'm always surprised how big of a difference sitting next to a fan makes in the somewhat less extreme 35C with low humidity, maybe even a bit better (but very localized) than just AC.

@Remittancegirl No, I absolutely don't think you're lying or anything like that. 38C dry-bulb is definitely happening in many places, also the humid ones.

Also, your hot-weather advice is very sound and good.

Just that during the peak-temperature hours, the relative humidity is likely even lower than 80% even during the wettests months, as 38C with even 80% is 34.8C, still on the edge of survival for humans. Vietnam is not listed to ever get above 34C in this list: https://en.wikipedia.org/wiki/Wet-bulb_temperature#Heat_waves_with_high_humidity

@Remittancegirl

Are you sure about those numbers? 38C with 90% humidity is 36.5C wet-bulb.

That is not survivable by a human and sweating does not cool one down at all in such a temperature. Also, according to Wikipedia, the highest recorded wet bulb temperature ever was 36.3C in UAE.
