Weather in September
Temperature
September heralds a minor drop in average high-temperature, sliding from August's hot 86.4°F (30.2°C) to a warm 81°F (27.2°C). During September, Readyville observes a consistent average nighttime temperature of 61°F (16.1°C).Heat index
For most parts of September, the heat index is estimated at a hot 86°F (30°C). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
