Why do Mumbaikars experience more humidity?

Humidity refers to the amount of water vapor present in the air. It's usually expressed as relative humidity (RH), a percentage showing how close the air is to being fully saturated with moisture. For example, 70 per cent RH means the air contains 70 per cent of the moisture it could hold at that temperature.

Mumbai is a coastal city surrounded by the Arabian Sea, which constantly adds moisture to the air. As summer progresses, sea surface temperatures rise, increasing evaporation and moisture in the atmosphere.
