Temperature

The onset of May brings a minor temperature shift, with the average high-temperature moving from a moderately hot 27.1°C (80.8°F) in April to a hot 30.5°C (86.9°F). In May, the average low-temperature is a warm 24°C (75.2°F).

Heat index

May's heat index is appraised at a very hot 39°C (102.2°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
