Indian Monsoon Has Not Failed in 13 Million Years, Professor Says

The Indian southwest monsoon has not failed in 13 million years, a professor from the Indian Institute of Technology said ^[1].

This historical perspective provides a baseline for understanding current weather patterns as India faces a delayed monsoon onset over Kerala. While short-term fluctuations cause immediate concern for agriculture and water security, the paleoclimate record suggests a system with immense long-term durability.

The professor said that while the monsoon may be late or weak in certain years, the system itself has persisted for 13 million years ^[1]. This continuity is based on paleoclimate records that track the movement of moisture and rainfall patterns over geological timescales ^[2].

However, this continuity does not necessarily imply stability. Records reveal that the system has undergone dramatic fluctuations over the millennia, including a major climatic event approximately 4,200 years ago ^[2]. These shifts demonstrate that while the monsoon always arrives, its intensity and timing can vary significantly.

Looking at the current cycle, the 2026 monsoon season — which runs from June to September ^[1] — is currently delayed over Kerala. Projections for the 2026 seasonal rainfall indicate a total of around 90% of the Long Period Average ^[1].

Experts said there is a margin of error of plus or minus four percent for this specific projection ^[1]. The current delay in the southwest monsoon's arrival is a point of concern for regional planners, but the historical data suggests the system will eventually deliver the necessary precipitation.
