Weather in September
Temperature
During August and September, Ingoumina experiences its warmest period, with an average high-temperature of 30.8°C (87.4°F).Heat index
The heat index value during September is calculated to be a very hot 37°C (98.6°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for 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.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. 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. Boost your sun resistance with garments that are densely woven yet spacious.
