Weather in September
Temperature
As August makes way for September, Buffalo's average high-temperature eases from a fiery hot 95.9°F (35.5°C) to a hot 88.7°F (31.5°C). In Buffalo, in September, the average low-temperature is an agreeable 68.9°F (20.5°C).Heat index
The heat index in September is evaluated at a very hot 102.2°F (39°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
