Weather in August
Temperature
Upon the onset of August, Marshall witnesses an average high-temperature of a moderately hot 84.6°F (29.2°C), showing a close resemblance to the prior month. Marshall's temperature tends to fall to an average low of 65.8°F (18.8°C) during the nights of August.Heat index
Throughout August, the heat index is estimated at a fiery hot 95°F (35°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for 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.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
