Hello,
when warm air cools down, the relative humidity inside increases. When it reaches 100%, it then condenses, usually on surfaces, in the house on walls. Since it is often cooler inside the house than outside in summer, exactly that happens.
When cold air is heated, the relative humidity decreases, which is why it becomes drier indoors when ventilating in winter.
However, I would not see the ventilation issue as too complicated, since temperatures inside and outside balance out over the long term in summer. The problem occurs permanently only in unsealed basements with cold exterior walls.
I hope I could help a little.
Regards
