Weather in September
Temperature
The average high-temperature shows a slight dip in September, from August's tropical 89.4°F (31.9°C) to a warm 82°F (27.8°C). Throughout September, an average nighttime temperature of 61.3°F (16.3°C) is experienced.Heat index
The heat index value for September is appraised at a tropical 87.8°F (31°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Note that heat index values are valued for light wind and location in the shade. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
