It is likely to be caused by a variation in temperatures of the outdoor and indoor air. Warmer indoor air cools window glass until it is below its dew point, which allows water molecules from the air to condense on the cold surface. This causes visible drops of fog or water on the window.

Fogging that occurs between the windowspanes is typically an indication of a weak seal in double or triple-paned windows. Materials that are insulating, like argon, between the panes of the windows are intended to stop heat from escaping through the glass. However, as the seal deteriorates over time, moisture is capable of passing through. This creates a visible fog, or condensation, in the middle of the glass. It is difficult to see through.
