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 haven’t been able to raise the humidity in our apartment anywhere near 40%, no matter when I ventilate. I assumed this is because the air is generally dry due to too little rainfall. No, the air is more humid in summer and drier in winter. Your feeling is not wrong, though. It actually feels the other way around because of the temperature.

I thought you’re not supposed to turn off a mechanical ventilation system because the ducts would become contaminated? Our last mechanical ventilation system didn’t even have an off switch. That’s also incorrect. Of course, you can turn it off. However, it is designed for continuous operation, which is why there is no clear on/off switch.
Yes...
Download the app "better ventilation," it's self-explanatory. Unfortunately, I have iOS and it’s not available there. I downloaded a similar app. This clearly shows my problem again. Currently, it doesn’t get cold outside, not in the evening, morning, or night. On top of that, there is high humidity outside—so what should I do?
Keep the windows closed during the day. Still, try to air out the rooms early in the morning and in the evening. An outside temperature of 14°C (57°F) with 80 percent humidity is actually drier than 22°C (72°F) with 58 percent humidity inside. Ventilating will make the indoor air drier, even if that is hard to believe....

We simply love the fresh air scented with forest and plants. The location and architecture make it possible, without any devices, to avoid the trap of trapped heat despite a high insulation standard.
