Weather in September
Temperature
September is marked by a subtle drop in average high-temperatures, transitioning from a tropical 88°F (31.1°C) in August to a moderately hot 82.6°F (28.1°C). In Summit Hill, September nights witness a steady temperature drop to an enjoyable 61.3°F (16.3°C).Heat index
September's mean heat index is computed to be a hot 89.6°F (32°C). With unrelenting exposure and activity, one might experience exhaustion, leading to potential heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
