Temperature

The transition from August to September brings an average high-temperature of a still warm 29.5°C (85.1°F), barely different from August's 29.3°C (84.7°F). The temperature during September experiences a small drop from daytime peaks, recording an average of 25.2°C (77.4°F) at night.

Heat index

The average heat index in September is evaluated at a sweltering 36°C (96.8°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. 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. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

The average relative humidity in September is 81%.

Ward off overexposure. Defence against solar harm is crucial. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
