Weather in September
Temperature
As September arrives, Lono's weather displays a minor decrease in high-temperatures, transitioning from August's tropical 91.4°F (33°C) to a moderately hot 85.5°F (29.7°C). The nighttime temperature in Lono, during September, averages of 64.8°F (18.2°C).Heat index
September's mean heat index is evaluated at a very hot 95°F (35°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle 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 'apparent temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for 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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
