Summer Heat Wave: What to Expect in June in India
India is bracing itself for another intense summer heat wave, with temperatures expected to soar in June. The India Meteorological Department (IMD) has forecasted an unusually high number of heatwave days from April to June, with the northwestern regions of the country likely to be the most affected[1][2][3].
Regional Impact
The heat wave is expected to impact several states, including Punjab, Haryana, Chandigarh, Delhi, Uttar Pradesh, Rajasthan, Bihar, and East Madhya Pradesh. Temperatures above 40°C are likely to be common in these areas, with some regions experiencing temperatures above 50°C[3][5].
Health Concerns
Heatwaves can have severe health impacts, particularly for vulnerable populations such as the elderly, children, and those with pre-existing medical conditions. The heat can exacerbate existing conditions such as cardiovascular, respiratory, and cerebrovascular diseases, as well as diabetes-related conditions[3][4].
Preparations
To mitigate the effects of the heat wave, it is essential for individuals to take precautions. These include staying hydrated, avoiding strenuous activities during peak heat hours, and seeking shade or air-conditioned spaces when necessary[3]. Governments and civic bodies are also implementing heat action plans to provide relief to affected populations[1][4].
Global Context
The heat wave in India is part of a broader global trend of intense heat events. The Southern Hemisphere is experiencing an unusually warm winter, while the Northern Hemisphere is witnessing a record-breaking hot summer, with many countries in Asia and Africa being severely affected[5].
Timeline
The heat wave is expected to persist throughout June, with a gradual reduction in conditions forecasted from the end of the month[5]. The IMD has predicted a 2-4°C fall in maximum temperatures over Northwest and Central India during the next five days[5].
