Weather in September
Temperature
The advent of September reveals an average high-temperature of a still tropical 32.9°C (91.2°F), showing minimal difference from the prior month. Throughout September, Da witnesses a nighttime temperature average of 23.4°C (74.1°F).Heat index
September's heat index is computed to be a blistering 44°C (111.2°F). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. 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. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Sunshine
The average sunshine in September is 9h.UV index
In Da, the average daily maximum UV index in September is 7. A UV Index reading of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for average individuals.Note: In September, the maximum UV index of 7 suggests these recommendations:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
