Weather in September
Temperature
Transitioning from August to September involves a subtle drop in average high-temperatures, descending from a hot 91.6°F (33.1°C) to a moderately hot 83.7°F (28.7°C). The month of September records an average low-temperature of 64.4°F (18°C) in Yale.Heat index
In September, the average heat index is computed to be a hot 89.6°F (32°C). Enduring exposure and continuous activity might cause a feeling of tiredness and induce heat cramps.Note that heat index values are valued for light wind and location in the shade. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
