Dense Fog Engulfs Northeast India: How Low Will Temperatures Drop?

For the next one week, Guwahati and the surrounding regions will go through normal peak winter conditions with dense cloud cover, fog during most hours of the morning, and a chilling effect, especially during morning and night.

The Regional Weather Forecasting Centre, Guwahati issued a forecast for the next seven days on 30th December 2025.

On December 30, the city, including the region of LGBI airport, will experience a partly clouded sky along with light rain and drizzle at intervals. The day temperatures will be around 19°C, though the night temperatures may fall to around 14°C. From December 31 onwards, the city can expect the region to be covered in fog during the early morning hours, which will continue right through to the first week of the next month.

Between January 1 and January 5, mornings will most likely start off with thick fog or mist to give way to partly clear skies as the day progresses. Daytime highs are forecasted to range from 19 to 22°C, with nights cooling to around 12–13°C until the weekend and early of next week.

The conditions are likely to be similar over the Dispur area and its surrounding localities. The year is likely to wrap up with cloudy skies and sporadic drizzle, continuing further into the New Year with persistent foggy mornings. During this time, day temperatures are likely to remain between 20°C and 23°C in Dispur, with night-time readings of about 13° to 15°, indicating a consistent winter chill throughout the region.

IIT Guwahati and its surrounding campus areas may also be affected by cold. Light rain or drizzle is most likely to prevail on December 30, coupled with moderate to dense fog in the morning, starting from December 31. The maximum temperature would hover between 19°C and 22°C while the early morning lows are around 12–14°C.

In response to the ongoing cold wave and low temperatures, the Kamrup (Metropolitan) district administration on Tuesday in a notification had announced a week-long closure of all government and provincialised schools in Guwahati.

The officials cited the move as a precautionary measure to protect students from severe cold and fog during early morning hours.

Overall, residents can expect a stable yet chilly spell over the next week, with cool nights, mild afternoons, and persistent morning fog. Reduced visibility in the early hours may occasionally affect road and air traffic, prompting commuters to exercise caution and take necessary precautions against the cold.

Northeast India Weather Outlook

Meanwhile, the India Meteorological Department (IMD) report issued on December 30, 2025, the broader Northeast region, including Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura, is set to experience typical winter conditions over the next few days. An upper air cyclonic circulation continues to persist over Northeast Assam at about 1.5 km above mean sea level, while a similar system over north Bangladesh has become less pronounced.

In the past 24 hours, light to moderate rain occurred at isolated places over Arunachal Pradesh and Assam, while Mizoram and Tripura saw occasional light showers. Meghalaya, Nagaland, and Manipur, in contrast, remained largely dry. Night temperatures rose appreciably over Nagaland, though in most other areas there were no significant changes. Overall, temperatures were above normal over Assam and Meghalaya and slightly above normal over Nagaland.

For the coming five days, Arunachal Pradesh is expected to see light to moderate rain or snow in the higher reaches, with isolated showers continuing in the plains. Assam may witness light rain at isolated locations on the first day, followed by generally dry weather. The rest of the Northeast, including Meghalaya, Nagaland, Manipur, Mizoram, and Tripura, is likely to remain predominantly dry. Shallow to moderate fog is expected at isolated pockets across the region, particularly during early mornings, which could lead to occasional reductions in visibility.

The IMD has also issued dense fog advisories for different states over the next few days. Assam, Meghalaya, Nagaland, Manipur, and Mizoram are likely to experience dense fog during the first two days, with Assam, Meghalaya, Manipur, and Mizoram continuing to see fog on the third day. On the fourth and fifth days, Meghalaya and Manipur are expected to witness dense fog. Maximum temperatures in the region are likely to fall slightly over the first two days and then stabilize, while minimum temperatures are expected to gradually decline from the third day onward and continue to remain low through the fifth day.

Overall, the Northeast is set to experience stable but chilly winter conditions, with cool nights, mild afternoons, and foggy mornings, creating a cold yet calm start to the New Year.
