Is 77% humidity normal?

Posted by CocosMumma@reddit | AskUK | View on Reddit | 4 comments

I have my bedroom window open during the day for aslong as I possibly can but the last 3 days the humidity level hasn’t gone down, I’m running an air dehumidifier when the window is shut and during the night. It’s been really warm today outside and I’m wondering if this is possibly adding to the humidity but I like opening my window during the day to air out my bedroom.

I have washing drying in my livingroom where the humidity levels are at 59%

Help please?
