Weather in September
Temperature
The shift from August to September is characterized by an average high-temperature of a still tropical 86.9°F (30.5°C), not significantly different from the 90.5°F (32.5°C) of August. An average nighttime temperature of 70.9°F (21.6°C) is witnessed in Hayes throughout September.Heat index
During September, the heat index is estimated at a torrid 102.2°F (39°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Factoring in the heat index, values are geared towards shaded areas with light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. 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 and potential dehydration arise when body heat gain eclipses its release capability.
