Heat index

For July, the heat index is evaluated at a scorching 107.6°F (42°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
