September brings relief from the relentless summer heat, with a reduction in temperature and a slight increase in rainfall volume to 5mm (0.2"). As the month transitions from summer to fall, the drop in average high temperatures combined with a nominal amount of rainfall paints a pleasing weather picture. The humidity level observes a slight dip, bringing a welcome change to the previous oppressive conditions. Despite the shift in season, the city enjoys extended daylight hours, albeit less than the preceding summer months.
Temperature
The start of September marks an average high-temperature of a still tropical 30°C (86°F), hardly distinguishable from the conditions in
August. September nights observe an average temperature dip to a refreshing 19°C (66.2°F).
Heat index
For September, the heat index is evaluated at a very hot 35°C (95°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
