Weather in September

September, the first month of the autumn in Rufe, is still a tropical month, with an average temperature fluctuating between 86.7°F (30.4°C) and 66°F (18.9°C).

Temperature

September's onset corresponds with a subtle shift in the average high-temperature, slightly moving from a tropical 93.9°F (34.4°C) in August to a still hot 86.7°F (30.4°C). Throughout the month of September, the nighttime temperature dips to an average of 66°F (18.9°C).

Heat index

The heat index in September is appraised at a very hot 96.8°F (36°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and 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 of high significance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
