Weather in September
Temperature
A subtle change in temperatures is noted as August gives way to September, with average highs reducing from a torrid 97.3°F (36.3°C) to a tropical 90.9°F (32.7°C). In the month of September, Alice witnesses a consistent average low-temperature of 75.2°F (24°C).Heat index

Continuous activity could trigger heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
