Weather in September
Temperature
The shift from August to September coincides with a small decrease in the average high-temperature, down to a warm 84.2°F (29°C) from a tropical 93°F (33.9°C). Nighttime temperature dips to a mean of 65.5°F (18.6°C) during September.Heat index
The heat index for September is estimated at a tropical 89.6°F (32°C). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.Note that heat index values are valued for light wind and location in the shade. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. 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. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
