Weather in September
Temperature
The transition to September results in a modest reduction in average high-temperature, moving from a sweltering 96.1°F (35.6°C) in August to a tropical 89.6°F (32°C). The average nighttime temperature in Magnolia, Texas, lowers to an agreeable 72.1°F (22.3°C) throughout September.Heat index
For most parts of September, the heat index is evaluated at a blistering 105.8°F (41°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.When referencing the heat index, its values are suitable for shady environments and light breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
