Weather in September
Temperature
September witnesses a gentle descent in average high-temperature, descending from August's hot 91.9°F (33.3°C) to a warm 84.2°F (29°C). Forgan, in September, observes a steady average low-temperature of 64.4°F (18°C).Heat index
For September, the heat index is evaluated at a tropical 86°F (30°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
