Weather in September

Chilson measures an average high-temperature of a warm 82.8°F (28.2°C) in September, nearly consistent with the preceding month. The temperature dips to an average of 63.7°F (17.6°C) during September nights.Heat index
September's heat index is calculated to be a hot 87.8°F (31°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
