Rainfall across 29 Iranian provinces has dropped by nearly a third since October, according to the Iran Meteorological Organization, as the country continues to struggle with water scarcity.

The country has experienced an overall rainfall reduction of 31.9% during this period, with the southern provinces of Sistan-Baluchestan and Hormozgan seeing the most dramatic declines at nearly 90% and just over three-quarters, respectively.

Mansour Shishehforoush, the Director General of Crisis Management for Isfahan Province, highlighted the severity of the situation earlier this year.

"Isfahan has a dry and semi-dry climate, and over 80% of its area is experiencing drought conditions," he said in July, noting that water tankers were being used to supply over 300 villages. Isfahan has since recorded a 68% reduction in autumn rainfall.

Despite the alarming trends, some regions have bucked the pattern. South Khorasan and Mazandaran have reported slight increases in rainfall, rising by 1.1% and 14.3%, respectively. These exceptions provide little relief, as other provinces, including Golestan and Gilan in the north, have experienced reductions of 16.6% and 7.8%, exacerbating the broader drought.

Sadegh Ziaeian, head of the National Center for Weather Forecasting and Crisis Management, flagged an additional concern: reduced water inflow into the Caspian Sea from neighboring countries, contributing to a decline in the sea's water level.

The rainfall deficit follows a year of weather extremes, including heavy flooding earlier in central and southeastern regions. These floods caused extensive damage, destroying homes and severing transport routes, highlighting the volatility of Iran's climate and the challenges it poses for crisis management.
