Weather in September
Temperature
September ushers in a minute temperature change, with average high-temperatures reducing from August's 94.3°F (34.6°C) to a still hot 88.7°F (31.5°C). Throughout the month of September, Telferner sees a steady low-temperature average of 73.2°F (22.9°C).Heat index
For September, the heat index is computed to be a blistering 104°F (40°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Heat index determinations are made taking into account the shade and light air movements. 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 'felt air temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
Humidity
The average relative humidity in September is 74%.Rainfall
The month with the most rainfall is September, when the rain falls for 16.2 days and typically aggregates up to 1.85" (47mm) of precipitation.Snowfall

Sunshine
The average sunshine in September is 8.5h.UV index
The average daily maximum UV index in September is 6. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for the ordinary person.Note: An average UV index of 6 in September transforms into this advice:
Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
