July, like June, is a hot summer month in Charleston, Arkansas, with an average temperature varying between 92.8°F (33.8°C) and 70.3°F (21.3°C).Temperature
The warmest period is July, when temperatures fluctuate between an average high of 92.8°F (33.8°C) and a low of 70.3°F (21.3°C).Heat index
July's heat index is calculated to be a burning hot 114.8°F (46°C). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
