Heat index

Throughout August, the heat index is estimated at a sweltering 96.8°F (36°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
Records show heat index calculations are tailored for shaded regions and mild winds. 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 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
