Weather in September
Temperature
Mamou's shift into September sets the average high-temperature at a still hot 86.5°F (30.3°C), a figure that deviates only slightly from August's 90.7°F (32.6°C). Throughout the month of September, Mamou reports a steady low-temperature average of 69.4°F (20.8°C).Heat index
September's average heat index is computed to be a fiery hot 100.4°F (38°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. 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 'feels like' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
