Heat index

The average heat index in July is appraised at a torrid 102.2°F (39°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
