August weather forecast
Lexington, SC

In August, Lexington's weather exhibits typical late-summer conditions. While the temperature maintains a high range between 71.8°F (22.1°C) and 89.8°F (32.1°C), a subtle cooling trend is evident. However, rainfall increases, and with it, the city's cloud cover, which provides a somewhat mitigating effect against the high daytime temperatures. The increased humidity and slower wind speeds lead to muggy conditions. In conclusion, while the month remains hot, the signs of the upcoming shift to fall become palpable towards the end.

Temperature

August in Lexington registers an average high-temperature of a still hot 89.8°F (32.1°C), slightly varied from July's 91.4°F (33°C). Nighttime temperatures in August average to a pleasant 71.8°F (22.1°C).

Heat index

In August, the heat index is calculated to be a blistering 105.8°F (41°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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 body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Sun protection is enhanced with clothing that boasts a tight weave yet offers a loose fit.
