Weather in September
Temperature
The transition to September results in a modest reduction in average high-temperature, moving from a tropical 86.5°F (30.3°C) in August to a warm 80.8°F (27.1°C). Moss temperatures generally rest at a low of 59.9°F (15.5°C) during the September nights.Heat index
The heat index value during September is calculated to be a tropical 86°F (30°C). Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.For clarity, heat index numbers account for light winds and areas under shade. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. 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 to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
