Weather in September
Temperature
With September's arrival, Idiofa, Democratic Republic of Congo, notes an average high-temperature of a hot 33.6°C (92.5°F), closely following the trend of the preceding month. Throughout September, Idiofa records an average temperature of 23.6°C (74.5°F) at night.Heat index
September's mean heat index is evaluated at a scorching 42°C (107.6°F). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Exercise precautions and adapt sun safety practices. Defence against skin and eye affliction is paramount. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Be alert to the fact! The reflection from snow can nearly double the UV radiation of the Sun.
