Weather in September
Temperature
The transition into September shows a subtle variation to a still warm 27.2°C (81°F) from August's 26°C (78.8°F) in the average high-temperature. Throughout September, the average low-temperature dips to an enjoyable 18.8°C (65.8°F).Heat index
Throughout September, the heat index is computed to be a tropical 30°C (86°F). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
