Weather in September
Temperature
With the onset of September, Lissie's average high-temperature slightly adjusts, moderately receding from August's 94.6°F (34.8°C) to a still tropical 88.2°F (31.2°C). During the month of September, an average temperature of 71.8°F (22.1°C) is noted during the nights.Heat index
The heat index value during September is appraised at an extremely hot 104°F (40°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. 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 physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
