Why South Carolina humidity makes window fogging so common

South Carolina humidity gives homeowners fewer dry hours to work with, so window glass and frames often stay damp longer than they would in a drier climate.

Air conditioning helps, but it can also create a sharp temperature difference between the inside of the glass and the air outside the window. That difference is what causes water to form.

Some rooms see it more than others. Kitchens, bathrooms, laundry rooms, and bedrooms with poor airflow tend to show the worst fogging.
