Heat index

May's heat index is calculated to be a blazing hot 50°C (122°F). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and 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 particular significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
