How it's used
While this term is technically accurate, locals almost always shorten it to just 濕度 in daily conversation. It is primarily used when discussing weather forecasts or specific scientific contexts. You will rarely hear people use the full four-character phrase in casual chat unless they are being intentionally precise.
Examples
The relative humidity is very high today, so the clothes are hard to dry.
Related words
Common phrases
high relative humidity
low relative humidity
Common mistake
Learners often try to use this term in casual settings where it sounds overly formal or clinical. Stick to 濕度 for everyday talk about the weather.
