Weather in September
Temperature
September signals a slight drop in average high-temperature, sliding from August's hot 94.6°F (34.8°C) to a still tropical 88.3°F (31.3°C). Brookshire's average low-temperature during September nights is observed to be an agreeable 71.8°F (22.1°C).Heat index
The heat index value during September is estimated at a scorching 104°F (40°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
