Weather in September
Temperature
The transition into September subtly indicates a reduction in the average high-temperature, down to a moderately hot 84°F (28.9°C) from August's hot 92.1°F (33.4°C). In Quinlan, an average nighttime temperature of 65.3°F (18.5°C) is expected during September.Heat index
September's average heat index is appraised at a tropical 87.8°F (31°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
