• The most proximate reasons for the lack of cyclone formation in the regions are sea surface temperatures that tend to run a shade cooler than ideal for tropical cyclone formation even in the southern summer.
• Also there is presence of cold current on both the South east pacific coast(cold peruvian current present here) and on the south Atlantic coast (Cold Benguela Current). The cold currents lower the surface temperatures of these coasts making them unfit for the breeding of cyclonic storms.
