humidity levels

Atmospheric moisture content

Humidity levels measure the amount of water vapor in the air, typically expressed as relative humidity—a percentage indicating how saturated the air is.

Weather reports cite humidity levels to indicate comfort: Humidity levels above 70% make the heat feel oppressive.

Indoor humidity levels affect health and home maintenance, with 30–50% considered ideal.
