‘Xiǎo yǔ’ literally means ‘small rain’—combining 小 (xiǎo), meaning ‘small’ or ‘light’, and 雨 (yǔ), meaning ‘rain’. It refers specifically to light, gentle rain with fine, scattered drops that fall slowly and do not significantly disrupt outdoor activities. Unlike heavier rain types like 大雨 (dà yǔ, heavy rain) or 暴雨 (bào yǔ, torrential rain), 小雨 is often associated with calm, overcast days and may last for hours without causing puddles or strong runoff.

This term is commonly used in weather forecasts, daily conversation, and descriptive writing to convey a soft, soothing atmosphere. It appears frequently in poetry and literature to evoke tranquility or quiet reflection. While it functions primarily as a noun, it can also act adjectivally in phrases like ‘小雨天气’ (xiǎo yǔ tiānqì, light-rain weather). It is neutral in register and appropriate in both spoken and written contexts.
