Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from a tropical 86.5°F (30.3°C) in August to a warm 81.1°F (27.3°C). During September, Oslin records an average temperature of 61.9°F (16.6°C) at night.Heat index
The heat index value for September is computed to be a tropical 86°F (30°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
