Weather in September
Temperature
The shift to September signals an average high-temperature of a still hot 87.1°F (30.6°C), subtly varied from August's 90.1°F (32.3°C). Throughout the month of September, Thames sees a steady low-temperature average of 72.3°F (22.4°C).Heat index
The average heat index in September is appraised at a very hot 102.2°F (39°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
