Weather in September
Temperature
September's climate shows a minor adjustment in average high-temperatures to a still moderately hot 29.3°C (84.7°F) from August's 29°C (84.2°F). The month of September sees a significant daily temperature drop, recording an average low-temperature of 16.6°C (61.9°F) in Mbaya, Democratic Republic of Congo.Heat index
The heat index in September is appraised at a torrid 35°C (95°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. 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. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
