Weather in September
Temperature
September's onset records an average high-temperature of a still tropical 87.8°F (31°C), a near match to August's 91.9°F (33.3°C). In September, the nighttime temperature lowers to an average of 67.3°F (19.6°C).Heat index
The heat index value for September is computed to be a torrid 100.4°F (38°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. 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 dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
