Weather in September

A moderate decline in the average high-temperature is seen during September, decreasing from a tropical 94.1°F (34.5°C) in August to a warm 84.9°F (29.4°C). During September, the nighttime temperature averages of 65.7°F (18.7°C).Heat index
In September, the heat index is appraised at a hot 89.6°F (32°C). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.Understand that the heat index values take into account shaded locations and mild winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
