Temperature

May introduces a minor temperature shift, with average high-temperatures adjusting from April's tropical 30.8°C (87.4°F) to a still hot 34°C (93.2°F). The nighttime temperature dips to a warm 24.8°C (76.6°F) on average during May.

Heat index

The heat index in May is estimated at a blazing hot 49°C (120.2°F). Stay vigilant: Heat cramps along with heat exhaustion are expected. Heatstroke may follow prolonged exertion.
Consider that heat index readings are for situations in the shade and light wind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. 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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
