Weather in September
Temperature
With the advent of September, Genoa experiences an average high-temperature of a still tropical 88.2°F (31.2°C), mirroring a close resemblance to the previous month. During the month of September, an average low-temperature of 70.7°F (21.5°C) is recorded.Heat index
September's average heat index is evaluated at an extremely hot 104°F (40°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Shun overexposure. Protection from sun ravages is indispensable. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
