Weather in September
Temperature
Transitioning from August to September involves a subtle drop in average high-temperatures, descending from a hot 89.8°F (32.1°C) to a moderately hot 82.4°F (28°C). Throughout September nights, a significant departure from daytime temperatures, with an average low of 60.4°F (15.8°C), is recognized.Heat index
September's average heat index is computed to be a hot 87.8°F (31°C). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.Heat index determinations are made taking into account the shade and light air movements. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
