Weather in September
Temperature
Maringouin commences September with an average high-temperature of a still hot 87.8°F (31°C), maintaining a close resemblance to the previous month. September witnesses an average nighttime temperature of 69.1°F (20.6°C).Heat index
September's average heat index is appraised at a blisteringly hot 105.8°F (41°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
