Temperature

July's arrival in New Delhi coincides with a soft drop in the average high-temperature, subtly decreasing from June's extremely hot 42.4°C to a sweltering 37.6°C. In New Delhi, an average nighttime temperature of 29.7°C is expected during July.

Heat index

The heat index value during July is appraised at a life-threatening hot 50°C. Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.
Be aware that heat index ratings are designed for shaded locations and minor breezes. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
