Weather in September
Temperature
Transition into September marks a drop in the average high-temperature, moving from a tropical 94.5°F (34.7°C) in August to a moderately hot 85.1°F (29.5°C). The low-temperature averages to a refreshing 65.8°F (18.8°C) during the nights of September.Heat index
The average heat index in September is calculated to be a tropical 89.6°F (32°C). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
