Overview
The India Meteorological Department (IMD) has issued its May 2026 monthly outlook, warning of above‑normal heatwave days in the foothills of the Himalayas, as well as in the east‑coast states, Gujarat and Maharashtra. At the same time, the department projects that the nation‑wide average rainfall for May will be above normal, and the southwest monsoon is expected to start over the Andaman and Nicobar Islands around 14‑16 May 2026.
Key Developments
- Above‑normal heatwave days projected for the Himalayan foothills, east‑coast states, Gujarat and Maharashtra.
- May‑wide rainfall likely to exceed the long‑term average across India.
- Monsoon onset over Andaman and Nicobar Islands anticipated between 14‑16 May 2026.
Important Facts
1. IMD bases its forecasts on a combination of satellite data, ground stations, and climate models.
2. Heatwave conditions are defined by sustained temperatures above the normal maximum for a given region, often leading to increased mortality, crop stress, and power demand.
3. An above‑normal rainfall outlook for May suggests a potentially stronger early monsoon, which can benefit sowing of kharif crops but also raises flood risk in low‑lying areas.
Exam Relevance
Understanding seasonal climate forecasts is essential for several GS papers. Heatwave and monsoon predictions directly influence agricultural planning, food security, and disaster preparedness—key topics in GS3. Moreover, the role of IMD exemplifies inter‑governmental coordination, relevant for GS2 (Polity) and governance questions.
Way Forward
- State governments should activate heat‑action plans,
