Temperature

Abuja marks the onset of September with an average high-temperature of a still warm 29.7°C (85.5°F), a subtle shift from August's 28.4°C (83.1°F). Throughout the month of September, the average temperature in Abuja dips to an agreeable 21.9°C (71.4°F) at night.

Heat index

Throughout September, the heat index is computed to be a sweltering 38°C (100.4°F). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
