IMD Forecasts Above‑Normal Heatwave in Himalayan Foothills & Coastal States; May Rainfall Likely Above Normal, Monsoon to Arrive Mid‑May over Andaman & Nicobar

<h2>Overview</h2> <p>The <strong>India Meteorological Department (IMD)</strong> has issued its May 2026 monthly outlook, warning of above‑normal heatwave days in the foothills of the <span class="key-term" data-definition="The lower slopes of the Himalayan mountain range, extending across northern India; climate here influences agriculture and water resources (GS3: Environment)">Himalayas</span>, 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 <span class="key-term" data-definition="The seasonal wind system that brings the majority of India’s rainfall, typically arriving in early June; its timing is crucial for agriculture (GS3: Environment)">southwest monsoon</span> is expected to start over the <span class="key-term" data-definition="A Union Territory comprising islands in the Bay of Bengal; early monsoon onset here often signals the broader monsoon progression (GS3: Environment)">Andaman and Nicobar Islands</span> around <strong>14‑16 May 2026</strong>.</p> <h3>Key Developments</h3> <ul> <li>Above‑normal heatwave days projected for the Himalayan foothills, east‑coast states, Gujarat and Maharashtra.</li> <li>May‑wide rainfall likely to exceed the long‑term average across India.</li> <li>Monsoon onset over Andaman and Nicobar Islands anticipated between <strong>14‑16 May 2026</strong>.</li> </ul> <h3>Important Facts</h3> <p>1. <span class="key-term" data-definition="India's national weather agency responsible for forecasting, climate monitoring and issuing warnings (GS3: Environment)">IMD</span> bases its forecasts on a combination of satellite data, ground stations, and climate models.</p> <p>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.</p> <p>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.</p> <h3>UPSC Relevance</h3> <p>Understanding seasonal climate forecasts is essential for several GS papers. <span class="key-term" data-definition="Seasonal climate patterns affect agriculture, water resources, disaster management and public health, all of which are covered under GS3: Economy and Environment)">Heatwave and monsoon predictions</span> directly influence agricultural planning, food security, and disaster preparedness—key topics in <strong>GS3</strong>.
