When I lived in London, I rented a flat that was in the loft of an old house.
There was no insulation in the sloped parts of the ceiling, only the flat middle bit had insulation.
Meaning winter was cold and summer was hot. In summer my ceiling was hot to the touch and in winter often my heating could not keep up. It would be running at full capacity and I could watch my thermostat temperature keep dropping.
I could keep my windows open all night and by morning it was still over 30 degrees inside, the heat would just never leave. I think because the wind would blow along the side of the house instead of directly at it so I got no airflow.
It still gets hot in my current flat, maybe 33 degrees but at least in winter it holds onto heat well. I can sleep with thin blankets.
Here is a photo of my thermostat at the peak I noticed.

(Assuming it’s cooler outside at night) the fix here is to induce the airflow you want by opening windows on opposing ends of your home and then placing a fan indoors ~1m away from one of the open windows blowing air out of the home. Outside of a custom-built solution, this is the most effective way to draw outside air in through the opposing window.
If there is a prevailing breeze along the path of airflow, use it to your advantage. Otherwise, draw air in through an occupied space you want to cool off the most, exhaust through a less occupied space.
