Weather in September
Temperature
Kisisi, Congo, registers the highest average temperatures during the month of September, with peaks of 32.3°C (90.1°F) and lows of 22.3°C (72.1°F).Heat index
The average heat index in September is calculated to be a torrid 39°C (102.2°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.In reference to the heat index, it's for places in shade and with a slight wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
