Patna: Following several days of minimum temperatures falling below 10°C, Bihar experienced a modest increase in temperatures on Wednesday as westerly winds diminished. However, this relief was temporary, as dense fog enveloped many areas of the state, leading hospitals from Patna to Gaya to report a significant increase in patients with heart and respiratory issues. Hospital records indicate that cases have surged by nearly 50% due to the combination of cold winds and worsening air quality, creating what doctors describe as “concerning conditions” for at-risk populations. The IMD has forecasted a rise in minimum temperatures by 1–3°C across most parts of the state within the next 24 hours, with no substantial changes anticipated afterward.
Maximum temperatures are predicted to remain stable over the coming three to four days. Over the past 24 hours, maximum temperatures have ranged from 25.5°C to 31.4°C, while minimums have varied from 12.2°C to 19.6°C. Eastern Bihar was the only area where temperatures showed little variation. Purnia recorded the highest maximum temperature in the state at 30.8°C, while Aurangabad noted the lowest minimum at 12.2°C. Fog severely impacted visibility on Wednesday morning, with Gaya reporting the lowest visibility at just 600 meters. Patna also experienced significantly reduced visibility and heavy dew accumulation in rural areas. Westerly winds of up to 25 km/h are expected to continue on Thursday, maintaining dry conditions.
Daytime temperatures are likely to remain between 26–32°C, while nighttime temperatures may range from 12–18°C. Districts in South Bihar, including Gaya, Nawada, and Aurangabad, will continue to face the most severe conditions of fog and cold. The IMD has warned that a low-pressure system may develop over the southeast Bay of Bengal around November 22. If it strengthens and moves northwest, Bihar could experience noticeable weather changes; however, forecasters caution that it is too soon to predict whether this will result in cloud cover, rainfall, or a further drop in temperatures. Given the hazardous combination of fog, cold, and pollution, doctors have advised residents to limit their exposure to cold air.
They recommend wearing coverings for the head, ears, and feet when outside, staying hydrated, engaging in light exercise, and maintaining a balanced diet. A physician based in Patna cautioned, “Even a slight lapse in care can trigger illness in this weather.”
