Weather in September
Temperature
The onset of September aligns with a soft reduction in the average high-temperature, gently falling from a tropical 93.7°F (34.3°C) in August to a moderately hot 85.1°F (29.5°C). Throughout September, Okarche witnesses a nighttime temperature average of 66.2°F (19°C).Heat index
During September, the heat index is evaluated at a tropical 89.6°F (32°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
