湿度 (shī dù): humidity

The humidity is very high today; I just finished mopping, and the floor is drying very slowly.

This type of tea is very sensitive to humidity, so it's best to store it in an airtight container.

In desert areas, humidity is low during the day but often rises at night, so the temperature difference between day and night is large.

The doctor suggested I use a humidifier because the humidity in the room is too low and my skin is always very dry.

During the rainy season, the humidity often exceeds 90 percent; the washed clothes hang on the balcony for two days and still don't dry.
