Fog and mist occur frequently on the higher regions of the Eastern Escarpment. Normally if the eastern wind starts blowing in the late afternoon, it carries moisture inland from the Indian Ocean. When the moisture is sufficient, it cools to a temperature where condensation takes place. It then resembles a cloud very close to or on the ground. When it is thick, visibility is very poor and it becomes hazardous to traffic, and hiking alike.

Mist is more common in valleys, along streams and rivers, and occurs more often at night, but can last all day.  When the temperature rises or the wind starts blowing, the mist will rise to a higher level and move away.

As trout favour cool temperatures, misty conditions are ideal for trout fishing. People also seem to like a cool misty weather in front of the fire with a glass of red.
