The Berg winds are winds that are forming in the plateaus deeper into the mainland. These winds move from the plateaus downwards towards the lowlands on the eastern coast of South Africa. The Berg winds are hot and dry winds and as they move they become even hooter because of the abiotic factors in the area.
These winds are very dangerous for the farming communities because they bring in very hot and dry weather with them. They dry out the soil and suck out every drop of moist out of it, and that combined with the hot weather they bring in is often devastating for the crops as they manage to destroy them, thus making a lot of damage for the farming communities that depend for their survival on those crops.
