Weather in October
Temperature
With the onset of October, Jacksonville's average high-temperature slightly adjusts, moderately receding from September's tropical 86.9°F (30.5°C) to a moderately hot 80.8°F (27.1°C). During October, Jacksonville records an average temperature of 65.8°F (18.8°C) at night.Heat index
The heat index value during October is evaluated at 84.2°F (29°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Understand that the heat index values take into account shaded locations and mild winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. 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. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
