Weather in September
Temperature
During September, Forest Hill observes a subtle ascent to a still hot 87.4°F (30.8°C) from August's 91.9°F (33.3°C) in the average high-temperature. An average low-temperature of 68.4°F (20.2°C) marks the month of September in Forest Hill.Heat index
The average heat index in September is estimated at a fiery hot 102.2°F (39°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
