Weather in September
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. A significant occurrence in September is the reduction of the UV index to 6.Temperature
Beaumont marks the start of September with an average high-temperature of a still tropical 88°F (31.1°C), hinting at a slight fluctuation from August's 93.2°F (34°C). Beaumont's temperature lowers to a mean of 71.8°F (22.1°C) during the nights in September.Heat index
In September, the heat index is computed to be a blistering 104°F (40°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
