The temperature remains relatively high, with warmer nights and hotter days.

Temperature

In September, the meteorological conditions in Ouara, Chad, subtly change with the average high-temperature edging from a hot 32.2°C (90°F) in August to a sweltering 35.3°C (95.5°F). Ouara's nighttime temperature during September is consistently averaged at a moderately hot 26.3°C (79.3°F).

Heat index

For September, the heat index is computed to be a blisteringly hot 40°C (104°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Take special precautions, as unprotected skin can be damaged and can burn quickly. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Boost your sun resistance with garments that are densely woven yet spacious.
