Weather in August
Temperature
Transitioning from July to August, Martinsburg observes an average high-temperature of a moderately hot 85.3°F (29.6°C), differing subtly from the previous month. During August, Martinsburg records an average temperature of 65.7°F (18.7°C) at night.Heat index
The average heat index in August is calculated to be a fiery hot 95°F (35°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.The standards for the heat index are set for locations in shade and under light breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. 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 highly critical for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
