Weather in September
Temperature
As Bristol welcomes September, the average high-temperature records at a still tropical 86.2°F (30.1°C), marking an insignificant deviation from the prior month. The temperature in Bristol lowers to an average of 69.8°F (21°C) during September nights.Heat index
The heat index for September is evaluated at a very hot 98.6°F (37°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Observations indicate that the heat index values are for shady locations with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
