Weather in September

With September's onset, the weather reveals a slight temperature decrease, transitioning from a hot 91.2°F (32.9°C) in August to a warm 84°F (28.9°C). Coal Hill's nights in September are distinguished by a pronounced temperature shift from the day, with an average low of 62.2°F (16.8°C).Heat index
September's heat index is computed to be a hot 91.4°F (33°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially crucial for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
