ᐅ Ventilation in summer without a mechanical ventilation system can be challenging

Hello,
I have done quite a bit of research but still don’t feel any wiser on this topic.
Many sources suggest ventilating early in the morning or late in the evening during summer because it is usually cooler outside than inside at those times. However, these sources often also mention that the outdoor humidity should ideally be lower.
But when I check the data, humidity is usually quite high in the early morning or evening during summer, or am I mistaken? So when exactly should I ventilate on hot summer days? Not ventilating at all doesn’t help either if the indoor humidity becomes too high (around 65 percent in the basement, for example).
Can someone explain this to me or give me some advice?
I would appreciate it.

I simply keep the controlled residential ventilation running continuously. Humidity doesn’t matter to me; I just always want fresh air in the house, both in summer and winter... The amount of heat brought into the house this way is minimal, as air is known to be a poor heat storage medium.
With passive cooling, it never gets really warm in my house anyway.

For an unconditioned basement, I would actually ventilate very sparingly in summer, possibly dehumidify additionally.
And regarding the house: the indoor air is simply more humid in summer; without air conditioning, there is not much you can do. Yes, I have a finished basement.
