El Nino alone does not cause torrential rains in Iran Raisi Ardakani, the father of the science of hydrogeology in Iran: the occurrence of El Nino does not necessarily mean heavy rains and floods in the country, and accurate forecasting of rains requires the study of various climate factors. There is a possibility of good rains in November, but we cannot expect heavy rains in all regions of the country. I expect next year's summer to be hotter than this summer in terms of ISNA temperature.
