Weather in September

September in Ruston signals the conclusion of the summer season, with falling temperatures. The daylight hours also begin to dwindle, reflecting the nearing arrival of autumn. There is a noticeable reduction in cloud cover, paving the way for clearer skies and less rainfall. Winds show a coordinated retreat with curtailing temperatures and cloud cover. Although humidity stays rather steady, at 72%, it offers a respite from the notoriously high humidity of summer.

Temperature

September's arrival subtly correlates with a reduction in the average high-temperature, down from 93.9°F (34.4°C) in August to a still tropical 88.3°F (31.3°C). Ruston witnesses a consistent average low-temperature of 67.1°F (19.5°C) throughout September.

Heat index

For September, the heat index is evaluated at a very hot 102.2°F (39°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
Note that heat index values are valued for light wind and location in the shade. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
