Weather in September
Temperature
The transition into September involves a small decrease in the average high-temperature, dipping slightly from a tropical 86.5°F (30.3°C) in August to a warm 80.6°F (27°C). The average nighttime temperature lowers to an enjoyable 62.1°F (16.7°C) throughout September.Heat index
September's mean heat index is evaluated at 80.6°F (27°C). One might feel worn out with persistent exposure and activity, resulting in heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
