An IMD official confirmed that weather models show over a 50% chance of La Niña forming between October and December 2025. La Niña is scientifically known to be associated with colder winters in India. While climate change can influence weather patterns, the prevailing trend during La Niña years is a noticeable drop in temperatures compared to neutral years. This suggests that India should prepare for a winter that could be colder than average, with the later months bringing more significant drops in temperature.

La Niña, a Spanish term meaning ‘Little Girl’, is a recurring phase of the El Niño-Southern Oscillation (ENSO) climate pattern. ENSO cycles, which include El Niño, La Niña, and neutral phases, occur naturally at irregular intervals, typically every two to seven years. The National Weather Service’s Climate Prediction Center has stated that La Niña conditions are currently present and are expected to persist through December 2025 to February 2026, with a likely transition to ENSO-neutral conditions in early 2026.
