Causes of humid weather

High air humidity: This is the main factor causing the humidity phenomenon. When the air humidity reaches a certain level, water vapor condenses into tiny droplets, clinging to surfaces and causing dampness.

Sudden temperature change: Large temperature differences between day and night can accelerate water vapor condensation.

Moist winds: Winds from the sea carry water vapor inland, and under favorable conditions, cause the humidity phenomenon.

Air pressure: Changes in air pressure also affect the condensation process of water vapor.

Impacts of humid weather
