Weather in September
Temperature
A moderate decline in average high-temperatures is noted in September, moving from a fiery hot 95.5°F (35.3°C) in August to a hot 87.3°F (30.7°C). Nemo, in September, observes a steady average low-temperature of 68.9°F (20.5°C).Heat index
Throughout September, the heat index is calculated to be a torrid 95°F (35°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

In Nemo, the average daily maximum UV index in September is 6. A UV Index of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for the ordinary person.Note: A maximum daily UV index of 6 during September morphs into the following directions:
Fend off overexposure. Sun protection is vital. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
