Heat index

The heat index value during September is computed to be a blistering 107.6°F (42°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
