Weather in September
Temperature
The average high-temperature shows a slight dip in September, from August's tropical 87.4°F (30.8°C) to a warm 81.7°F (27.6°C). In Triune, September is marked by an average low-temperature of 62.8°F (17.1°C).Heat index
In September, the heat index is calculated to be a hot 86°F (30°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
