Temperature

Picayune's warmest month, August, generally records average temperatures ranging from a high of 91.9°F (33.3°C) to a low of 75°F (23.9°C).

Heat index

Throughout August, the heat index is calculated to be a burning hot 116.6°F (47°C). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
