Temperature

The arrival of September marks a slight shift to an average high-temperature of a still tropical 33.9°C (93°F) from August's 33.7°C (92.7°F). The average temperature drops to a moderately hot 24.8°C (76.6°F) during the night in the month of September.

Heat index

The heat index value for September is computed to be a life-threatening hot 48°C (118.4°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.
Note that heat index values are valued for light wind and location in the shade. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to 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.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
