Weather in September
Temperature
Ségou's entry into September measures an average high-temperature of a still tropical 31.9°C (89.4°F), closely parallel to the preceding month. An average nighttime temperature of 22.5°C (72.5°F) is recorded during September.Heat index
September's heat index is computed to be a blazing hot 45°C (113°F). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
