Heat index

During August, the heat index is calculated to be a very hot 96.8°F (36°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. 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. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
