Weather in September

September, the first month of the autumn in Innis, is also a hot month, with an average temperature varying between 69.1°F (20.6°C) and 87.3°F (30.7°C).

Temperature

The transition into September is marked with an average high-temperature of a still tropical 87.3°F (30.7°C), showing an insignificant shift from August's 90.9°F (32.7°C). Throughout September, Innis registers a consistent average low-temperature of 69.1°F (20.6°C).

Heat index

September's average heat index is appraised at a blistering 104°F (40°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
