Humidity in house

[rufusgti]

I purchased a humidity gauge a week or so ago as I'm always getting condensation on the Windows inside. I'm getting readings of between 55-70% depending on the temperature, cooking, baths/showers etc etc. This seemed a bit high from reading around online so plugged in a dehumidifier. It's been running for about 24 hours and collected about 2 litres of water so it's doing its job. I set it to 55% to help keep it a bit lower. Today however I'm still getting readings of 60-63%.

I''m wondering what is actually a likely figure to be reaching on a wet day in December in Wales. I was shocked to find that the forecast for today was 80% and tomorrow 90%. Now I'm wondering if I'm being a bit optimistic at reaching 55% in a 1940's 3 bed semi at this time of year.

Any views or advice welcome.

I don't think I have a problem as such. There's no mould growth except on the windows if I don't wipe them down once a week. But I was led to believe 60+ is on the high side. We have a good quality powerful bathroom fan and we open the windows in the mornings. Keep the place warm and have a log burner. But 4 people, cooking, washing, laundry creates moisture. Just wondering if it's worth keeping the dehumidifier pumping away trying to reach 60% when it's 80% outside.
