Weather in September
Temperature
The commencement of September includes a gentle temperature shift, with the average high-temperature dropping a bit from a hot 86.5°F (30.3°C) in August to a moderately hot 81.1°F (27.3°C). September nights are marked by an average low-temperature of 61.9°F (16.6°C).Heat index
During September, the heat index is computed to be a tropical 86°F (30°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. 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 extremely significant for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
