Weather in September
Temperature
September signals a slight drop in average high-temperature, sliding from August's tropical 88.3°F (31.3°C) to a moderately hot 81.1°F (27.3°C). In September, the nighttime temperature lowers to an average of 61.9°F (16.6°C).Heat index
For most parts of September, the heat index is appraised at 84.2°F (29°C). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
