Weather officials said temperatures could fluctuate slightly, with maximum and minimum temperatures likely to fall by around 1 to 2 degrees Celsius in some areas. The difference between daytime and nighttime temperatures is also expected to become more noticeable as the post-monsoon season progresses.
On Sunday, October 18, dry weather prevailed across Bihar. Patna and several other districts experienced sunshine alongside intermittent cloud cover, resulting in mild warmth during the day. However, cooler conditions continued during the late-night and early-morning hours.
The maximum temperature declined in 16 districts on Sunday. Patna recorded a maximum temperature of 33°C, while Bhabua registered the state’s highest maximum temperature at 36°C.
Weather System Over Bay of Bengal
According to the weather department, a cyclonic circulation persists over the west-central Bay of Bengal and adjoining coastal areas of Andhra Pradesh and Tamil Nadu. Under its influence, Bihar is expected to continue experiencing predominantly dry and normal weather conditions.
There is currently no significant possibility of rainfall in Patna or other parts of the state, and temperatures are likely to remain within a relatively stable range over the next few days.
Why Is Bihar Experiencing a Change in Weather?
The gradual transition in weather conditions follows the withdrawal of the southwest monsoon. With clearer skies allowing stronger sunshine during the day, temperatures continue to feel warm in the afternoon. At the same time, shorter days and falling nighttime temperatures are contributing to cooler mornings and evenings.
This seasonal transition typically brings a wider gap between daytime and nighttime temperatures, creating warm afternoons and relatively cool nights across the state.
Bihar Weather Forecast for October 20–23
On October 20, Bihar is expected to record a maximum temperature of around 32°C and a minimum temperature of approximately 23°C. Daytime sunshine may continue to produce a mild feeling of warmth.
On October 21, maximum temperatures are likely to remain largely unchanged, while minimum temperatures could decline by around 1°C. Generally stable weather conditions are forecast to continue on October 22 and 23, with no major temperature changes currently indicated.
The weather department has also indicated that a western disturbance could influence temperatures after about a week, potentially bringing a further decline in temperatures and a slight increase in the feeling of cold.
For now, residents across Bihar can expect predominantly dry weather, warm afternoons and relatively cool mornings and nights.
