Patna: Large parts of Bihar are reeling under intense heatwave-like conditions, with nearly 23 districts reporting extreme temperatures and hot winds, according to the India Meteorological Department (IMD).
Rohtas district’s Dehri recorded the highest temperature at 44°C, marking one of the hottest days of the season. In Patna, the maximum temperature stood at 40.6°C for the fourth consecutive day, with forecasts indicating it could rise further to around 41°C over the next 24 hours. Officials warned that strong westerly winds may intensify heatwave conditions, especially during the afternoon.
The IMD has issued a red alert for heatwave conditions in five districts, where temperatures are likely to exceed 44°C. Authorities have cautioned that prolonged exposure to hot winds could increase the risk of dehydration and heatstroke.
Amid the scorching conditions, parts of northeast Bihar witnessed brief relief. Kishanganj experienced heavy rainfall accompanied by strong winds and lightning on Saturday morning, bringing down temperatures and easing humidity. The weather department has also predicted light rain with gusty winds in Kishanganj, Purnia, and Katihar.
Ground reports from districts highlight the severity of the heat. In Nalanda, harsh sunlight and high temperatures have led to deserted streets during peak hours, while in Jehanabad, schoolchildren were seen using umbrellas to shield themselves from the sun.
Weather experts attribute the current conditions to multiple active systems. A low-pressure area persists at around 0.9 km above sea level across Bihar, Jharkhand, and West Bengal. Additionally, a cyclonic circulation over eastern Uttar Pradesh has merged with this system. Strong westerly winds, blowing at speeds of 80–90 knots at higher altitudes, are further influencing the weather pattern.
These systems have led to contrasting conditions across the state, with cloud formation and sporadic rainfall in north Bihar, while south Bihar continues to experience intense heat.
Historical data indicates that April temperatures have been rising steadily in recent years. The 44°C recorded in Dehri this month has surpassed previous records. Earlier, Buxar had recorded 44.2°C in April 2024, while temperatures in recent years ranged between 42.4°C and 43.8°C across districts like Rohtas, Aurangabad, and Buxar.
The IMD has also issued alerts for Supaul, where rainfall, thunderstorms, and lightning are expected between April 26 and 29. Meanwhile, relatively cooler winds in parts of Nalanda have provided slight respite despite high temperatures.
Meteorologists differentiate between a ‘hot day’ and a ‘heatwave.’ A hot day refers to above-normal temperatures causing discomfort, while a heatwave is declared when temperatures exceed 45°C or remain above 40°C for prolonged periods, often accompanied by hot winds, increasing health risks.
Residents have been advised to avoid direct sun exposure during peak hours, stay hydrated, and take necessary precautions as extreme weather conditions persist across Bihar.
