Weather in September
Temperature
September is marked by a subtle drop in average high-temperatures, transitioning from a tropical 92.8°F (33.8°C) in August to a moderately hot 84.7°F (29.3°C). Throughout September, Cimarron City witnesses a nighttime temperature average of 65.5°F (18.6°C).Heat index
In September, the average heat index is evaluated at a tropical 89.6°F (32°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. 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 quite important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
