Assam is experiencing an unusually warm November this year, with winter arriving much later than usual. November normally brings cool mornings, foggy skies and a noticeable drop in temperature. But this time, the weather has remained warm, leaving people wondering when winter will finally begin.
Meteorologists say the delay is caused by the absence of cold winds from the west, higher humidity and unusually warm air. Just a few years ago, people could feel the early signs of winter as soon as autumn ended. Foggy mornings, gatherings around fires and children wearing sweaters to school were common. But this November, these familiar scenes are missing.
Even during the festival of Raas, which is usually associated with winter nights and warm clothing, people were seen enjoying ice cream, cold drinks and chilled fruit juice. Instead of jackets, sweaters, woollen caps and mufflers, many attended the events wearing half-sleeve shirts. Security guards, villagers coming from naamghars, and students going for tuition—all scenes that once showed winter clothing—are now missing.
Experts say such changes suggest a clear pattern of climate change. The India Meteorological Department (IMD) has warned that winter may be delayed across many parts of India this year. According to IMD’s latest climate outlook, the northeastern region, including Assam, will experience higher-than-normal temperatures in both day and night during November. This means winter in Assam will be warmer than usual.
IMD attributes this pattern to the effect of the Pacific Ocean phenomenon La Niña, which is expected to continue through November and December 2025. La Niña influences wind patterns and rainfall, resulting in unusual temperature changes.
Environmentalists believe widespread deforestation, hill cutting and rapid construction are major contributors to these abnormal weather conditions. Reduced rainfall during summer and weaker winter conditions now appear to be the new normal for the region.
Studies also warn of serious long-term effects. According to climate research, Assam has been experiencing a yearly temperature rise of about +0.01°C. Experts fear that by 2040, some parts of Assam could witness an increase of up to 0.83°C. The state’s historical records show that the minimum temperature in November 2012 dropped to 10.9°C, while the coldest December recorded was 5°C in 1975 — temperatures that now seem increasingly distant.
Rainfall patterns have also changed. Assam saw significantly reduced rainfall in July and August this year, adding to concerns about climatic imbalance.
Climate change is not only altering the pattern of hot and cold seasons but also affecting daily life, agriculture, business and even local industries. Experts warn that without urgent environmental protection and sustainable development measures, the impact on Assam’s economy and lifestyle will continue to deepen.
