Weather in September
Temperature
The shift from August to September coincides with a small decrease in the average high-temperature, down to a still tropical 87.3°F (30.7°C) from a hot 93.4°F (34.1°C). The month of September records an average low-temperature of 65.8°F (18.8°C) in Troy.Heat index
September's average heat index is calculated to be a torrid 98.6°F (37°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Consider that heat index readings are for situations in the shade and light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
