Delhi’s October 2025 Weather Anomaly: Record Pollution Amid Unseasonal Rain and Temperature Swings
October typically ranks among Delhi’s driest months alongside November, yet the national capital witnessed an unprecedented weather pattern in 2025. Despite the monsoon’s timely withdrawal on September 24, Delhi experienced significant rainfall during the first week of October. This rare precipitation was swiftly followed by an extended dry spell that continues to grip the city and its suburbs, with no immediate relief in sight. Compounding these conditions, The Prime News Network reports that pollution levels have reached their worst threshold in recent years for this time of year.
Unusual cyclonic activity across both the Bay of Bengal and Arabian Sea during October altered regional wind patterns, resulting in persistent cloud cover, dense mist, and reduced heat accumulation. Meteorological data reveals Delhi’s average daytime temperature settled at 31.4°C—notably below the historical norm of 33°C. Minimum temperatures hovered at 20.1°C, slightly exceeding the standard 19.5°C benchmark. This temperature configuration mirrors records previously observed in 2022. In stark contrast, October 2024 had registered as the hottest in recent memory with average temperatures surpassing 35°C.

The Prime News Network’s meteorological team anticipates low-level winds will revert to normal westerly flow within 24 hours, though light winds will persist. This shift may trigger marginal nighttime cooling, potentially driving minimum temperatures down to 17°C from today’s 21.6°C reading. A more significant development looms as a western disturbance is forecast to reach Delhi on November 4, 2025. This system will temporarily reverse wind patterns to southeasterly flow, elevating nighttime temperatures on November 4-5. Early projections indicate the disturbance may bring light rainfall—though confirmation requires closer monitoring. Following this weather event, a decisive temperature drop is expected from mid-November onward as winds intensify, finally ushering in the anticipated winter chill that residents eagerly await.
