Weather in August

The last month of the summer, August, is also a hot month in London, Arkansas, with an average temperature ranging between min 68.7°F (20.4°C) and max 90.5°F (32.5°C).

Temperature

August's advent presents an average high-temperature of a still tropical 90.5°F (32.5°C), indicating a slight variation from the conditions of the previous month. Despite higher daytime temperatures, nighttime averages fall to an agreeable 68.7°F (20.4°C) in August.

Heat index

August's mean heat index is calculated to be a scorching 109.4°F (43°C). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
