Weather in September
Temperature
A minor decrease in the average high-temperature is observed during September, shifting from a tropical 88.3°F (31.3°C) in August to a moderately hot 81.9°F (27.7°C). Brandsville, during September nights, observes an average temperature of 60.8°F (16°C).Heat index
The heat index value during September is computed to be a tropical 86°F (30°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. 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.
