Weather in September
Temperature
The average high-temperature for September is a still tropical 87.8°F (31°C), closely aligning with the temperature of the preceding month. Throughout the month of September, Tallahala reports a steady low-temperature average of 68°F (20°C).Heat index
For September, the heat index is appraised at a blisteringly hot 104°F (40°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.The standards for the heat index are set for locations in shade and under light breezes. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
