Patna: Winter has arrived in Bihar weeks ahead of time, with temperatures across the state dropping to levels usually seen in late December and January. The minimum temperature in Gaya fell to 11.5°C on Monday — the lowest in the state — while Patna’s Air Quality Index (AQI) climbed to 293, placing it firmly in the ‘poor’ category. The combination of chilly weather and rising air pollution has made conditions increasingly uncomfortable for residents.
Meteorological data shows night temperatures between 10°C and 15°C in several districts, a phenomenon that meteorologists attribute to northwesterly cold winds and a shift in wind patterns that are rapidly cooling the air across Bihar.
In addition to Gaya’s sharp temperature dip, West Champaran recorded 11.8°C, East Champaran 12°C, Rohtas 12.1°C, Nawada 12.7°C, and Patna 13.4°C, marking the earliest onset of winter in recent years. The India Meteorological Department (IMD) has warned that temperatures could drop further by 2–3°C over the next 72 hours, with westerly winds blowing at 25–30 km/h likely to intensify the chill.
Dense morning and evening fog is expected to blanket several parts of the state, reducing visibility and potentially disrupting travel. While the sun is expected to appear during the day, its warmth will remain weak due to haze and moisture, keeping daytime temperatures below normal.
Meanwhile, air quality has deteriorated sharply across Bihar. In Patna, Sammanpura’s AQI hit 293 and Danapur’s 212, both in the poor category. Officials say vehicle emissions, construction dust, and stagnant air are the primary culprits. As wind speeds slow and temperatures drop, pollutants become trapped near the ground, worsening air quality.
Residents across Patna, Gaya, and Nawada have begun donning sweaters and mufflers, with sales of winter clothing on the rise. Bonfires and hot tea stalls have reappeared on street corners, signaling a full-fledged seasonal shift.
Agricultural experts, meanwhile, suggest that the early onset of winter may benefit Rabi crops, but warn that prolonged fog and moisture could pose risks if temperatures continue to fall sharply.
The IMD has issued a “cold night” advisory for several districts, urging residents—particularly the elderly and children—to stay indoors during early mornings and late evenings and take precautions against cold winds.
