Weather in September
Temperature
The arrival of September sees a recorded average high-temperature of a warm 82.8°F (28.2°C), showing little divergence from the previous month's conditions. In Winnabow, September is marked by an average low-temperature of 69.3°F (20.7°C).Heat index
In September, the average heat index is evaluated at a hot 89.6°F (32°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Note that heat index values are valued for light wind and location in the shade. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
