Weather in September
Temperature
The transition into September is accompanied by a slight temperature decrease, with the average high-temperature shifting from a tropical 90°F (32.2°C) in August to a moderately hot 82.9°F (28.3°C). An average low-temperature of 63°F (17.2°C) is observed during September nights.Heat index
September's average heat index is computed to be a hot 87.8°F (31°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Note that heat index values are valued for light wind and location in the shade. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
