Q. Does temperature, humidity and rainy season effect the speed of sound in air?

Solution
Yes these effect the speed. As humidity increases , the velocity of sound increase and vice-versa.
In SI units with dry air at 20°C (68°F), the speed of sound c is 343 meters per second (m/s).
In room temperature air at sea level, for example, sound travels about 0.35 percent faster in 100 percent humidity (very humid air) than it does in 0 percent humidity (completely dry air).
Water molecules are much less massive than oxygen, nitrogen or carbon dioxide molecules, and so the greater the fraction of air that is made up of water vapor, the less mass per unit volume, and the less dense the air becomes. Lower density translates into faster sound wave travel, so sound waves travel faster at high humidity.
