September weather forecast
Materi, Benin

September in Materi, Benin signals a transition from the intense wet season. Rainfall lessens perceptibly to 125mm (4.92"), following a reduction in humidity levels. The reduced cloud coverage allows an increase in sunshine hours to 8.2 hours. The temperatures remain lower than in the first half of the year, but warm weather persists. A drop in wind gusts to 8.8km/h (5.5mph) points to calmer atmospheric conditions.

Temperature

The transition into September shows a subtle variation to a hot 30.5°C (86.9°F) from August's 28.9°C (84°F) in the average high-temperature. The average temperature during September nights is registered at a pleasant 21.9°C (71.4°F).

Heat index

The heat index value for September is evaluated at an extremely hot 40°C (104°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Humidity

The average relative humidity in September is 82%.
