Weather Factoid: Why does frost form first on car windshields even if the temperature is a little above freezing and other objects do not ice up? The physics are rather complicated, but we’ll try to explain. It has to do with two distinct properties of the windshield itself. First, the angle: as dew develops, horizontally inclined surfaces like windshields release the heat caused by evaporation (dew formation) faster than vertical planes like side windows. On a side window, for instance, the heat slowly rises against the glass, keeping it frost free. But on a windshield, because of its angle, the heat created is quickly dissipated directly into the air, which super-cools the glass surface. The other property of windshields specifically is that dew, which turns into frost, gathers more readily because of tiny pits in, and grit on, the glass.
