Weather in September
Temperature
An average high-temperature of a still tropical 86.7°F (30.4°C) marks September, exhibiting a close resemblance to the conditions in August. During September, the nighttime temperature averages of 67.5°F (19.7°C).Heat index
For most parts of September, the heat index is computed to be a sweltering 96.8°F (36°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. 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 hold particular importance 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.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
