Patna: Bihar is witnessing a gradual change in weather conditions, with cooler mornings and nights but warm afternoons due to strong sunshine. Following the withdrawal of the southwest monsoon, westerly winds have begun to influence the state’s weather, bringing a slight chill during the early morning hours.
According to the India Meteorological Department’s (IMD) Meteorological Centre, light rain is likely in five districts of Bihar on Thursday, October 15. The districts are Jamui, Munger, Banka, Khagaria and Bhagalpur. Light drizzles are also possible in some parts of North Bihar on October 17 and 18.
Despite the changing weather, daytime temperatures are expected to remain relatively high, particularly in areas receiving strong sunshine.
Why Is Bihar’s Weather Changing?
The changing weather conditions are mainly attributed to the withdrawal of the southwest monsoon and a shift in wind direction. Westerly winds, along with overnight cooling, are contributing to relatively pleasant mornings and nights.
However, strong sunshine during the day continues to raise temperatures, resulting in noticeable differences between daytime and nighttime conditions.
Residual moisture in the atmosphere and local weather conditions may also lead to isolated light showers in some districts, even after the monsoon’s withdrawal.
