Weather in September
Temperature
September's arrival coincides with a soft drop in the average high-temperature, subtly decreasing from August's hot 90.1°F (32.3°C) to a warm 82.6°F (28.1°C). During September, Coldwater records an average temperature of 62.1°F (16.7°C) at night.Heat index
In September, the heat index is estimated at a tropical 86°F (30°C). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.Heat index readings emphasize conditions of light breezes and shaded spots. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
