Weather in September
Temperature
September observes an average high-temperature of a still tropical 86.4°F (30.2°C), marking an insignificant difference from August's 89.4°F (31.9°C). Nightly temperatures drop to an average low of 67.5°F (19.7°C) in September.Heat index
The heat index in September is calculated to be a sweltering 96.8°F (36°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
