Temperature

Sampaguita experiences a subtle adjustment in high-temperatures to a still tropical 30.1°C (86.2°F) with the onset of September, maintaining near parity with August's 30.1°C (86.2°F). Sampaguita, during September nights, observes an average temperature of 24.8°C (76.6°F).

Heat index

September's average heat index is evaluated at a very hot 39°C (102.2°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
Data suggests that the heat index is set for environments in shade and with a light wind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
