Weather in September
Temperature
The beginning of September subtly marks a decrease in the average high-temperature, transitioning from a torrid 95.5°F (35.3°C) in August to a tropical 88.3°F (31.3°C). During the month of September, La Grange experiences a steady low-temperature average of 71.1°F (21.7°C).Heat index
The heat index value for September is appraised at a torrid 102.2°F (39°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.One should consider that heat index numbers are for shaded settings and light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly relevant to 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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
