Weather in September
Temperature
The arrival of September is marked by a minor reduction in average high-temperature, sliding from a torrid 95.2°F (35.1°C) in August to a tropical 89.1°F (31.7°C). Splendora usually reports an average low-temperature of 71.2°F (21.8°C) during the month of September.Heat index
September's average heat index is estimated at a scorching 105.8°F (41°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
