What are the cause of condensation on the outside of windshield?

Condensation on the outside of a windshield occurs when warm, moist air comes into contact with the cooler surface of the glass, causing the water vapor to cool and condense into tiny droplets. This often happens in the early morning or evening when temperatures drop, particularly in humid conditions. Additionally, factors such as temperature differences between the inside and outside of the vehicle can contribute to this phenomenon.
