Temperature

The shift into May is marked by a modest rise in the average high-temperature, moving from April's warm 29.3°C (84.7°F) to a hot 32.6°C (90.7°F). The average low-temperature of 24.2°C (75.6°F) is witnessed during May.

Heat index

The heat index value for May is calculated to be a life-threatening hot 45°C (113°F). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Remember, however, that not all shade structures offer full protection. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
