Weather in September
Temperature
The arrival of September signals a subtle shift in temperature, down from a tropical 86.5°F (30.3°C) in August to a moderately hot 81.1°F (27.3°C). Nighttime temperature experiences an average drop to an enjoyable 61.7°F (16.5°C) in September.Heat index
The heat index value during September is appraised at a tropical 86°F (30°C). Continuous activity in exposure could lead to a feeling of fatigue and heat cramps.Factoring in the heat index, values are geared towards shaded areas with light breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', arises from combining readings of air temperature and relative moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
