In New Delhi, Palam area recorded 47.6-degree Celsius, six notches above the normal, followed by Aya Nagar, Safdarjung and Lodhi Road
Delhi, Rajasthan, Haryana, Punjab and parts of Uttar Pradesh have been experiencing blistering heat for days with temperatures soaring over 45 degrees Celsius in some places.
This season, the temperatures did not rise the way it usually does in north and central India because of significant rainfall activity during April that continued till mid-May
But 2015 saw the worst heatwave in India since 1992, striking areas from Delhi to Telangana and killing 2,081 people. It was the fifth deadliest in world history
When the air temperature exceeds 35°C, the body relies on the evaporation of water - mainly through sweating - to keep core temperature at a safe level
Heat waves due to anti-cyclones in north India are a regular phenomenon during the April-May period
But India simply cannot afford to ignore the new health and livelihood challenges
Bundelkhand is the worst hit with mercury logging an average 47 degrees Celsius
As per records, June 5 is the hottest World Environment Day in the last four years in Delhi
