High humidity significantly impacts night-sky visibility by increasing atmospheric moisture, leading to light scattering and cloud formation. Stargazers in areas with elevated humidity may find it challenging to observe stars and planets clearly. The increased moisture in the air causes light to scatter more readily, making it difficult to see stars and planets clearly. Clouds, which often form in humid conditions, further obscure the night sky. These conditions are typical in regions with tropical or subtropical climates, where humidity levels are consistently high. Observers in these areas may need to wait for drier conditions to enjoy optimal stargazing experiences.
