Assam Experiences 26% Rainfall Deficit in March, Heatwave Threatens Amid Rising Temperatures
Why in News?
- Due to the significant climatic shifts currently affecting Assam, particularly the state’s substantial rainfall deficit and the early onset of a heatwave. These developments are creating serious concerns for the region, as they are impacting both the environment and the economy.
Important Key Points:
-
Rainfall Deficit:
-
March 2025 Shortfall: In March 2025, Assam experienced a rainfall deficit of approximately 26%, with actual precipitation recorded at 0.7 mm on March 29, 2025, compared to the average of 1.5 mm for this period.

Early Onset: The heatwave arrived unusually early in 2025, with temperatures soaring to 38.7°C in Mumbai on February 26, marking a 5.9°C increase above the average.
-
Northeast India Impact: The northeastern states, including Assam, are experiencing atypical heat, with temperatures reaching up to 40°C. This anomaly is attributed to a “heat dome effect,” a high-pressure system causing hot and dry conditions.
-
Fatalities in Assam: The intense heat has led to tragic outcomes in Assam, with three heat-related deaths reported in Jorhat within a two-day span.
Projected Climate Trends:
-
Temperature Rise: By 2040, some districts in Assam may see mean annual temperatures rise by up to 0.83°C, posing challenges to the state’s economy and ecosystems.
