Weather in September
Temperature
Thames's shift into September is marked by a subtle change to a still tropical 87.1°F (30.6°C) from August's 90.1°F (32.3°C) in temperature. During the month of September, an average low-temperature of 72.3°F (22.4°C) is recorded in Thames.Heat index
The average heat index in September is appraised at a fiery hot 102.2°F (39°C). Emphasize additional safety, risk of heat cramps and heat exhaustion is high. Continuous activity might result in heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. 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. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
