Weather in August
Temperature
The average high-temperature is a still hot 91°F (32.8°C) in August, hardly different from the 91.4°F (33°C) recorded in July. Sallis's temperature in August lowers to a consistent average of 71.2°F (21.8°C) during the nights.Heat index
The heat index in August is calculated to be a burning hot 113°F (45°C). Stay on guard: Heat exhaustion and heat cramps are predicted. Ongoing effort can cause heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
