Weather in September
Temperature
As August turns into September, the average high-temperatures rest at a still tropical 88.5°F (31.4°C), showing a minor variation from the prior month. Silsbee observes an average nighttime low-temperature of 70.7°F (21.5°C) during the month of September.Heat index
September's mean heat index is calculated to be an extremely hot 105.8°F (41°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
