Chennai Braces for Moderate Rain and Lightning as Northeast Monsoon Kicks Off Oct 16, 2025
When India Meteorological Department (IMD) issued its latest warning, Chennai residents suddenly found themselves checking umbrellas instead of just their phones. The agency, headquartered in New Delhi, forecast moderate rain, frequent thunderstorms and lightning across the city on October 16, 2025, marking the official onset of the Northeast Monsoon. The alert matters because, despite the rain, the Times of India reported that the Air Quality Index will stay in the ‘good’ range, offering a rare breath of fresh air amid humidity. Chennai, sitting at roughly 13.08°N, 80.27°E, can expect highs of 31‑32 °C and lows of 26‑27 °C, with partly‑cloudy skies that will occasionally break into intense downpours. The city’s drainage crews from the Greater Chennai Corporation are already on standby, wary of flash‑flood risks that have haunted the region in past monsoon seasons.
