Why is There Condensation On My Window?

Condensation on windows in winter is a common occurrence. Here's why it happens, explained simply: Imagine a glass of sangria in summer, with water forming on the glass. The same goes for your windows in winter. When warm air from the house meets the cold glass, it cools. The humidity in the air is transformed into small drops of water on the glass. This is called condensation.
