Weather in September
Temperature
The average high-temperature shows a slight dip in September, from August's 94.6°F (34.8°C) to a still tropical 88.5°F (31.4°C). Geneva temperatures generally rest at a low of 68.2°F (20.1°C) during the September nights.Heat index
The heat index in September is estimated at a blistering 104°F (40°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
