What is the range of relative humidity typical for tropical climates?

• A. 0%-100% relative humidity
• B. 0%-50%
• C. 50%-100%
• D. 60%-90%

Answer: (A)

Humidity in tropical climates stays high because hot air can hold more moisture, and there is abundant evaporation from oceans and dense vegetation plus frequent rainfall. This combination keeps the air near saturation most of the time, so relative humidity remains elevated rather than drying out. In practice, tropical climates typically show relative humidity around 60–90%, with values frequently reaching 100% during heavy rainfall. The idea of a 0–100% range isn’t representative of usual tropical conditions, since the air tends to stay moist rather than spanning the entire possible spectrum. This high humidity is what gives tropical regions their characteristic muggy feel, especially during the wet season.
