According to the IMD, a heatwave occurs when air temperatures reach levels that pose a risk to human health upon exposure. It is typically defined quantitatively by temperature thresholds in a region, either in absolute terms or in comparison to average temperatures.

A ‘heatwave’ is recognised when the maximum temperature in a location reaches 40 degrees Celsius or higher for plains and 30 degrees Celsius or higher for hilly regions.
