Weather in September
Temperature
Transitioning from August to September, Louise observes an average high-temperature of a still hot 87.1°F (30.6°C), differing subtly from the previous month. Louise cools down to an average low-temperature of 67.3°F (19.6°C) throughout the month of September.Heat index
For most parts of September, the heat index is evaluated at a fiery hot 98.6°F (37°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for 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.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Take precautions and utilize sun safety practices. Protection against skin and eye damage is required. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
