ᐅ Moisture Levels in New Buildings Increase During Wet Weather – Experiences?

Hello,
I am a tenant and recently moved into a newly built apartment, where, as in my previous home, I set up a hygrometer. While the humidity in my previous apartment mostly stayed around 40-45%, which was rather dry, in the new apartment it sometimes ranges from 40-55%, but during wet weather it remains consistently between 60 and 70%. The strange thing is that the humidity inside only rises this much during wet weather and then does not drop again until the weather changes.
There is effective cross-ventilation every morning and evening, with a full air exchange. Over the course of the first “wet day,” meaning about 12 to 14 hours, the humidity rises significantly, even though practically no moisture is generated indoors and the apartment is actually quite large. If the weather stays humid, the apartment remains damp for days until the weather improves.
Currently, I’m not quite sure why this happens or if I am doing something wrong or could do better. In any case, anything above 60% humidity in living and working spaces is far from comfortable and, of course, promotes mold growth. Right now, the humidity is actually a solid 70%. Since I’m a tenant, I do have a relatively easy way out if this really turns out to be a serious problem. What’s strange to me is that there is no ventilation system at all. However, I lack the technical knowledge overall. Does anyone here have experience and can offer advice?
Thank you!

But is this a problem, or a defect, or can it be normal?It would be unusual if it weren’t 😉 (unless you have a ventilation system, which makes it even drier in winter).
