What Causes ‘Fog’ and Why Does It Happen More in Some Places?

Fog happens when the air gets cool and holds less water. Imagine you’re breathing out on a cold day, your breath turns into little clouds of water. Fog is like that, but it’s in the sky! When warm, wet air meets cooler air, the water turns into tiny drops that float around, making everything look hazy. Places near oceans or lakes get fog more often because there's lots of water to make those tiny droplets.
