The effect of tropical cyclones on South Africa The tropical cyclone season in our part of the world is from November to April, with the peak frequency in January and February. Only tropical cyclones moving into the Mozambique channel influence South Africa's weather. When this happens, we usually experience dry weather over the interior because of the subsiding air surrounding a tropical cyclone. Only a few move in over or close enough to the land to cause destruction, and then usually north of the 25°S latitude. In such cases, the Northern Province, Mpumalanga and KwaZulu-Natal may experience destructive winds and the risk of flooding. Significant tropical cyclones that had such an effect on South Africa was Domoina which occurred in January 1984, Imboa in February 1984 and more recently Eline in February 2000. Although the track of a tropical cyclone is very erratic, the Weather Service can still issue timely warnings to the public if a tropical cyclone is approaching densely populated. Tropical cyclones seldom reach South Africa. However a number of tropical cyclones do move into the Mozambique Channel and have an effect on areas surrounding the channel.
