Weather in September
Temperature
With the onset of September, a modest change to a still hot 32.1°C (89.8°F) from August's 31.6°C (88.9°F) is noted in high-temperature. The low-temperature average for Dinga Ioba during September stands at a moderately hot 23.2°C (73.8°F).Heat index
During September, the heat index is estimated at a blazing hot 47°C (116.6°F). Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. 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. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
