Weather in September
Temperature
The beginning of September brings a slight decrease in the average high-temperature, transitioning from 93.4°F (34.1°C) in August to a still hot 86.5°F (30.3°C). In September, Reno experiences a temperature dip to an average of 67.1°F (19.5°C) at night.Heat index
Throughout September, the heat index is appraised at a sweltering 95°F (35°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
