Weather in September
Temperature
The arrival of September signals a subtle shift in temperature, down from a tropical 92.8°F (33.8°C) in August to a warm 84.6°F (29.2°C). Nighttime temperature dips to a mean of 65.7°F (18.7°C) during September.Heat index
The heat index in September is appraised at a tropical 89.6°F (32°C). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.Note that heat index values are valued for light wind and location in the shade. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a numerical representation of warmth when taking temperature and moisture levels into account. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. 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 are particularly relevant to children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
