Window Condensation

When inside air comes in contact with the windows, it cools down and can't hold onto its moisture. It leaves this moisture on the windows as condensation or “fog.” Your windows may also fog up on the outside at night, when the temperature drops and the dew falls.

Likewise, people ask, how do you keep your windows from fogging up in the rain?

Heat – Turning the heater on will help to warm the windows so they are above the dew point. Don't recirculate – While the recirculate setting on your car's heater might make it warm up more quickly, it means that the moisture stays inside the car! Turn this off to let the fresh air in and the water out.
