As August turns into September, the average high-temperatures rest at a still tropical 33.5°C (92.3°F), showing a minor variation from the prior month. September nights bring a pronounced temperature shift, with averages hovering around an agreeable 21.2°C (70.2°F).

Heat index

The heat index for September is computed to be a blisteringly hot 41°C (105.8°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

September and October, with an average relative humidity of 61%, are the least humid months.

September and October are months with the least rain when the rain falls for 4.1 days and typically aggregates up to 3mm (0.12") of rain.

Note: A daily high UV index of 7 in September leads to these guidelines:
Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. 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.
