Weather in September
Temperature
September sees a slight reduction in average high-temperature, with a shift from a tropical 87.4°F (30.8°C) in August to a moderately hot 81.7°F (27.6°C). An average minimum temperature of 62.4°F (16.9°C) marks the month of September.Heat index
The average heat index in September is computed to be a tropical 86°F (30°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
