The arrival of September brings an average high-temperature of a still tropical 86.4°F (30.2°C), subtly diverging from August's 90.5°F (32.5°C). Throughout September, an average nighttime temperature of 69.8°F (21°C) is experienced.

Heat index

Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
