Weather in September
Temperature
With the start of September, Hackley measures an average high-temperature of a still tropical 87.4°F (30.8°C), not significantly differing from August's 91°F (32.8°C). In September, Hackley reports a consistent average low-temperature of 69.6°F (20.9°C) during the nights.Heat index
Throughout September, the heat index is appraised at a torrid 102.2°F (39°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
