July is the month when Duke's temperatures reach their peak, with averages of 90.1°F (32.3°C) and lows of 69.4°F (20.8°C).Heat index
For most parts of July, the heat index is appraised at an extremely hot 109.4°F (43°C). Stay vigilant: Heat cramps along with heat exhaustion are expected. Heatstroke may follow prolonged exertion.For clarity, heat index numbers account for light winds and areas under shade. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Also note that objects like parasols or canopies might not provide complete sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
