Weather in September
Temperature
The beginning of September brings a slight decrease in the average high-temperature, transitioning from a hot 94.3°F (34.6°C) in August to a still tropical 88.9°F (31.6°C). Saint Maurice experiences an average temperature drop to an agreeable 68°F (20°C) during September nights.Heat index
In September, the heat index is appraised at an extremely hot 104°F (40°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
