With the onset of September, Beaumont starts to witness a drop in the high summer temperatures. The weather remains on the hotter side, albeit with less humidity. A decrease in rainfall accompanies the slowly cooling temperatures. Fall's approach also reduces daylight duration, now available for 12.3 hours per day.

Temperature

The commencement of September in Beaumont records an average high-temperature of a still tropical 88°F (31.1°C), barely varying from August's 93.2°F (34°C). Beaumont's average low-temperature during September nights is observed to be a pleasant 71.8°F (22.1°C).

Heat index

For September, the heat index is computed to be an extremely hot 104°F (40°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
