What relative humidity means
Relative humidity (RH) is how much water vapor the air holds compared with the most it could hold at that temperature. Warm air can hold more, so the same moisture gives a lower RH in the afternoon and a higher RH at night.
Healthy indoor humidity
Indoors, 40–60% is generally recommended: drier air irritates the eyes and throat, while damper air encourages mold and dust mites. For outdoor comfort, the dew point is a better guide — see the dew point calculator.

Frequently Asked Questions
How do you calculate relative humidity?
From temperature and dew point with the Magnus formula: RH = 100 × e^(17.625·Td/(243.04+Td)) ÷ e^(17.625·T/(243.04+T)).
What is a good humidity level indoors?
About 40–60%.
Why is humidity highest in the early morning?
The air is coolest then, so the same amount of moisture is closer to saturation.
