The heat index for August is estimated at a blisteringly hot 42°C (107.6°F). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.Understanding the heat index involves considering values for shaded locales with light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. 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.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. Attention! UV radiation is ramped up when reflecting off sand and water surfaces.
