Weather in September
Temperature
The commencement of September brings an average high-temperature of a still tropical 32.3°C (90.1°F), marking an inconsequential divergence from August. During September, the temperature tends to dip to an average of 22.9°C (73.2°F) at night.Heat index
In September, the average heat index is computed to be a blazing hot 47°C (116.6°F). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.One should consider that heat index numbers are for shaded settings and light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. 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.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
