Temperature

The advent of September observes an average high-temperature of a still tropical 88.2°F (31.2°C), nearly identical to August's 90.1°F (32.3°C). During the nights in September, Saint Catherine experiences a consistent average temperature of 72.7°F (22.6°C).

Heat index

September's average heat index is computed to be a blisteringly hot 105.8°F (41°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
