Out all day so the doors and windows have been shut... 22.3c.

I think in decades to come when I'm looking to retire, Scotland will be high on my list! For whatever reason whenever I've been it reminds me of parts of Canada, albeit without the extreme climate.

Meanwhile down here in the muggy old SE of England, it's actually cloudy for once. Not that it helps matters as there's no wind and indoors it's still uncomfortably warm...

Might sound a bit daft but putting a good electrical fan out on the windowsill outside during the evening & night and facing it inwards can help to blow in some cooler air from outside. I did this a lot last summer when it was particularly warm and it did help a small bit.

23C in the living rm atm .. I took pity on the missus wrapped in her blanket - so lit the wood burner this evening. Temp. prior to that was around 18.5 C! Expecting more in the way of solar input here this week as we finally lose that moist cloudy feed off the Irish Sea .. I've told the missus we won't need any heating on next week ...

20.4 C here in the living rm atm .. the 69% Rel. humidity making it feel pleasantly warm - even the missus isn't sat under her blanket tonight! Thanks to the copious sunshine today, the house walls are acting like a storage heater

22.8c this afternoon when plums and apples being cooked .

Been in the Twenty Two's  inside today.....

Inside Shed  17.4c.

Bungalow is 20.oc average throughout.

It's been pretty pleasant for September so far - temperatures have been peaking around 24C upstairs, but have falling back to 21C by the time I go to bed.

Downstairs it's currently 22C and upstairs it's also 22C (I've just opened the windows and it's 14C outside, so it should cool down nicely up there).

The coldest spot of the house is the (east-facing) kitchen, at 20C.

It'll be a while before heating is needed here!

Sounds good. That is nice and warm.

Stone farmhouse with double glazing and good roof+loft insulation but solid stone walls.
Right now:

17C in computer room (upstairs bedroom, no heat yet)
19.7C in living room with small fire in woodburner this evening.
16.5C in unheated kitchen.
14C in unheated but heavily insulated outbuilding.

Outside now 11.3C, min today 2.8C. Max today was 13.7C

Outside average last 24 hours: 9.7C
Month av: 10.9C
Year av to date: 8.6C

About now the daytime solar gain becomes almost insignificant even when it's sunny as windows are relatively small by modern standards.
If no heat is introduced the mass of stone internal walls cools steadily, needing a great deal of energy to warm up again.
By November regardless it becomes difficult to achieve 'modern' indoor comfort levels except in 2 or 3 rooms.
Most heating here is from 'free' wood in two woodburners, one of which also heats water and radiators in some rooms.
'Free' wood does need to be dry and stored undercover.
Gathering and cutting takes at least a week but not all at once!

The great majority of the wood is dead from fallen branches and increasingly coppiced material from trees I planted for the purpose in the 70s, 80s and 90s. There is no mains gas here and oil though cheap now is volatile and cannot always be delivered in prolonged snowy spells. So wood and a small amount of coal is easily the best option.

In the past a lot of fires were kept going with peat, not least because there were far less trees - and bringing in coal was more difficult.
In theory rights of turbary (peat cutting) on the moors are still held by most houses near it, but rarely exercised in this area.
Peat is not a high output fuel and also needs careful drying and handling.
