September slowly transitions the climate from overwhelmingly wet to significantly less rainy conditions. Rainfall drops sharply to 53mm (2.09") compared to the previous month, setting the stage for the upcoming dry period. Daylight hours begin to reduce, signaling the end of the warm, wet season, and initiating the countdown to the colder months. Even though temperatures remain elevated, they trend downwards. The variation between sunshine and rains adds a delightful unpredictability to the city's weather.

Heat index
The average heat index in September is computed to be an extremely hot 43°C (109.4°F).
Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Take all critical precautions, unprotected skin might burn swiftly. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage. Even under cloud cover, use sunscreen with at least an SPF 30 generously and reapply frequently post every swim or outdoor exercise.
