The weather in Bihar is slowly shifting as the state transitions from the humid monsoon months to the cooler days of early winter. Over the past week, a clear contrast has been noticed between daytime warmth and nighttime chill. Days are still somewhat hot, but mornings and late evenings bring a mild cold breeze. In several districts, dense fog and mist have started appearing during the early hours, signaling the beginning of seasonal change.
According to the latest Bihar Weather Report, this transition could intensify in the coming days. The Indian Meteorological Department (IMD) has predicted light rainfall and cloud cover in many parts of the state as temperatures continue to drop. The gradual fall in minimum temperature indicates that winter is approaching, and people can expect cooler mornings ahead.
Minimum Temperature Continues to Drop
The IMD’s latest observation shows that the minimum temperature in most districts of Bihar has been falling steadily. While the days remain warm, nights are becoming cooler. This decline in temperature has made the early morning hours slightly chilly, especially in rural regions and open areas.
Despite this, weather experts suggest that the initial days of Chhath Puja—particularly Nahay-Khay and Kharna—are expected to remain normal without major weather disturbances. However, during the main rituals, particularly on the days of Sandhya Arghya (evening offering) and Pratah Arghya (morning offering), there is a chance of light drizzle and partial cloud cover. The IMD has indicated that after October 25, Bihar may witness intermittent rain in some areas, which could slightly affect the festive activities of Chhath devotees.
Possibility of Rain During Chhath Puja
The Chhath Puja, one of the most important festivals in Bihar, is expected to be influenced by changing weather conditions this year. The IMD’s Bihar weather forecast suggests that rainfall activity might begin on October 27. On that day, light rain is likely in the districts of Jamui and Bhagalpur. The weather could remain cloudy in nearby areas as well, creating a slightly humid environment.
By October 28, the rain belt is expected to expand, covering parts of Nawada, Jamui, and Banka districts. These areas may experience scattered showers and cloudy skies throughout the day. Farmers and residents in these regions are being advised to stay updated with daily weather alerts since light rain could impact agricultural activities and preparations for the festival.
As per the Bihar Weather Report, on October 29, rainfall may spread from North to South Bihar. The forecast indicates that most districts could experience cloudy weather, light drizzles, and occasional showers. Northern regions such as Sitamarhi, Madhubani, Darbhanga, and Muzaffarpur might see mild precipitation, while the southern parts including Bhagalpur, Banka, and Jamui could receive more consistent rainfall.
Interestingly, a few western districts like West Champaran, East Champaran, and Gopalganj are likely to remain dry, as per the current weather models. This means that devotees in these areas might enjoy a relatively clear sky during Chhath Puja. Still, a light breeze and mild cloud cover may persist, reflecting the changing seasonal dynamics.
Daytime Heat Persists Amid Weather Transition
Despite the drop in nighttime temperature, the daytime heat in Bihar continues to be noticeable. The maximum temperature across many regions remains between 32 and 36 degrees Celsius. This means that afternoons can still feel warm, particularly in cities such as Patna, Gaya, and Bhagalpur.
According to the Bihar Meteorological Department, the weather remains partially cloudy across much of the state. Winds are blowing at a moderate pace, providing some relief from the humidity. The minimum temperature ranges between 20 and 24 degrees Celsius, which is typical for late October. However, mornings and evenings are expected to get cooler as the month ends and November begins.
In the early hours, dense fog has been reported in parts of northern Bihar, including Sitamarhi, Madhubani, and Motihari. These foggy conditions could affect visibility for early commuters, especially those traveling by road. The IMD has urged drivers to exercise caution during the morning hours.
Weather Impact on Chhath Festivities
Chhath Puja holds deep cultural and religious importance for the people of Bihar. This four-day festival is dedicated to the worship of the Sun God and is celebrated with immense devotion and traditional rituals near rivers and ponds. Weather conditions play a crucial role during this time, as devotees perform rituals standing in water during sunrise and sunset.
The Bihar Weather Report suggests that although rainfall may not be heavy, even a light drizzle could make it challenging for devotees, particularly during the Sandhya Arghya and Pratah Arghya ceremonies. In past years, similar weather patterns have occasionally disrupted festival preparations, but this year the administration has already started making arrangements to manage any weather-related inconvenience.
Authorities in Patna, Muzaffarpur, and Bhagalpur have been directed to ensure proper cleanliness and drainage near riverbanks. Temporary shelters are also being planned for devotees in case of rain. The Bihar State Disaster Management Department is closely monitoring the weather forecast and coordinating with local administrations to ensure smooth celebrations.
Seasonal Shift and Its Broader Impact
The shift in Bihar’s weather pattern is part of the broader transition from monsoon to winter. After months of humidity and frequent rainfall, dry winds are now beginning to dominate the state’s climate. Meteorologists say that this seasonal transition is often marked by fluctuating temperatures, mild fog, and occasional rain spells.
For farmers, this weather holds mixed implications. While light rain could benefit rabi crop sowing in some areas, excessive moisture might delay harvesting in others. In parts of southern Bihar, especially in Banka, Nawada, and Jamui, farmers are keeping a close watch on the rainfall forecast to plan agricultural activities accordingly.
Forecast for the Coming Week
According to the IMD’s weekly Bihar Weather Report, most regions will witness partly cloudy conditions with occasional sunshine. There is a moderate chance of rain between October 27 and October 29. The temperature is expected to remain stable with a gradual drop in the minimum temperature by two to three degrees Celsius.
By the end of October, the weather will start becoming cooler across the state. Morning fog will likely increase, especially in riverine areas. Cities such as Patna, Gaya, and Muzaffarpur may experience foggy mornings followed by sunny afternoons. The temperature variation between day and night will continue, reflecting the state’s typical pre-winter climate.
The Bihar Weather Report clearly indicates that the state is entering a transitional phase. With cooler mornings, foggy conditions, and occasional rainfall, residents can feel the onset of winter. The IMD’s alert about possible rain during Chhath Puja has created a cautious atmosphere among devotees and local authorities.
While the overall weather remains favorable for the festival, light showers may add an unpredictable twist to the celebrations. Residents are advised to stay updated with daily weather forecasts and plan their rituals accordingly.
As Bihar prepares to celebrate Chhath Puja with devotion and enthusiasm, nature too seems to be joining in with its seasonal rhythm—balancing warmth and coolness, sunshine and rain. Whether the sky remains clear or cloudy, the spirit of Chhath in Bihar will continue to shine through every offering made to the rising and setting sun.
