Weather in September

The first month of the autumn, September, is also a hot month in Hanene, Senegal, with an average temperature varying between 33.9°C (93°F) and 24.8°C (76.6°F).

Temperature

Entering September, the average high-temperature is recorded at a still tropical 33.9°C (93°F), exhibiting a minimal shift from August's 33.7°C (92.7°F). The average low-temperature of 24.8°C (76.6°F) is witnessed during September.

Heat index

September's mean heat index is computed to be a burning hot 48°C (118.4°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.
Understanding the heat index involves considering values for shaded locales with light wind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Note: The maximum UV index of 7 during September translates into these guidelines:
Shun overexposure. Protection from sun ravages is indispensable. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear.
