Assam Faces Unprecedented Heatwave Amidst Rainfall Deficit

Severe Heatwave Grips Assam

Jorhat, June 13: Currently, Assam is experiencing extreme heat, particularly in the upper regions, where temperatures have surged significantly above the usual levels for this time of year. Experts have linked this unusual heatwave to a notable lack of rainfall in June and a weakened monsoon system, which has intensified the discomfort for residents throughout the state.

In the past week, temperatures have continued to climb, with Jorhat recording a blistering 38.2°C on June 12, marking the highest temperature for this period in recent memory. Typically, June temperatures would remain around 37°C or lower, thanks to regular rainfall, which has been conspicuously absent this year.

Dr. R.L. Deka, a professor at the Agricultural Meteorology Department of Assam Agricultural University, noted that since June 8, temperatures in upper Assam have been approximately 6°C above average.

He indicated that this unusual increase is directly linked to the lack of rainfall during June, a month usually characterized by heavy downpours.

“In most years, rainfall helps regulate temperatures. However, this year, upper Assam has seen a significant drop in precipitation,” he remarked.

Dr. Deka further explained that lower Assam has experienced slightly cooler temperatures due to sporadic rainfall in certain areas.

“While the entire state is experiencing higher than normal temperatures, the rainfall in lower Assam has somewhat moderated the heat there,” he added.

Interestingly, the weather patterns in June have been influenced by unusual conditions in May. The state saw excessive rainfall last month, which typically leads to the formation of low-pressure areas that attract monsoon winds in early June.

This year, however, monsoon winds arrived in Assam prematurely on May 26, well ahead of the expected June 5 onset. This early arrival weakened the monsoon in June, resulting in reduced rainfall when it was most needed.

Another factor contributing to the heat is the seasonal solar intensity. With June 21 being the longest day of the year, the lack of cloud cover has intensified solar radiation, further heating the ground and air.

The state has also recorded low atmospheric moisture levels, which adds to the discomfort and exacerbates the heat.

Dr. Deka pointed out that the absence of water vapor in the atmosphere has intensified the conditions.

“With low humidity, clear skies, and intense solar radiation, this combination is driving the current situation,” he stated.

However, there may be some relief on the way. A bulletin from the India Meteorological Department (IMD) indicates that widespread rainfall is anticipated across most of Assam on June 14, 15, and 16. Dr. Deka expressed optimism that these showers will provide much-needed relief, at least temporarily alleviating the oppressive heat.
