Weather in September
Temperature
September is marked by an average high-temperature of a warm 82.4°F (28°C), almost identical to the preceding month. Throughout September, the temperature falls to an average low of 63°F (17.2°C).Heat index
September's average heat index is estimated at a hot 87.8°F (31°C). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
