Weather in September
Temperature
September experiences an average high-temperature of a still tropical 87.8°F (31°C), barely different from August's 91.6°F (33.1°C). In September, the temperature in Pecan Grove drops to an average of 67.6°F (19.8°C) at night.Heat index
For most parts of September, the heat index is calculated to be a sweltering 102.2°F (39°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', quantifies the warmth felt when relative humidity is considered. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
