Delhi recorded a temperature of 21°C in September, marking the lowest September temperature in 18 years and signalling an early onset of winter.
Delhi’s average temperature on September 1st fell to 21°C, the lowest reading for the month in the past 18 years. Meteorological data shows that the city’s temperatures have been trending lower this season, with several days recording highs below 25°C.
The drop is attributed to a shift in the monsoon trough and a strengthening of the western disturbances that bring cooler air from the north. Local officials warn that the early cold spell could affect agriculture in the surrounding plains and may lead to increased demand for heating.
Weather experts note that such early winter conditions are becoming more common in the northern plains, reflecting broader climate variability. Residents are advised to prepare for cooler nights and to monitor official weather updates for any sudden changes.
