Weather in July
Temperature
In Fayetteville, temperatures reach their average annual highs in July, measuring 86.5°F (30.3°C) and a minimum average of 68.5°F (20.3°C).Heat index
The heat index value for July is appraised at a very hot 100.4°F (38°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
