When stating the weather is humid, what other term could be used?

The term "moist" is synonymous with "humid" as both describe the presence of moisture in the air. When the air is humid, it means that there is a high level of water vapor, which makes the environment feel damp and sticky. "Moist" conveys a similar idea, indicating that something contains a noticeable amount of moisture.

In contrast, the other terms—cold, sunny, and clear—refer to different weather conditions that do not imply humidity. Cold refers to a low temperature, sunny describes the absence of clouds or precipitation, and clear indicates visibility conditions without obstructions or haze. Thus, "moist" is the only alternative that closely aligns with the concept of humidity in terms of atmospheric conditions.
