Weather in September
Temperature
The transition from August to September sees average high-temperatures adjusting to a moderately hot 85.5°F (29.7°C), from a not significantly different 89.2°F (31.8°C). September nights cool down to an average low-temperature of 67.8°F (19.9°C).Heat index
The average heat index in September is computed to be a sweltering 95°F (35°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
Humidity
The average relative humidity in September is 73%.Rainfall
The month with the least rainfall is September, when the rain falls for 11.3 days and typically collects 1.3" (33mm) of precipitation.Snowfall

Sunshine
In September, the average sunshine is 8.7h.UV index
The average daily maximum UV index in September is 6. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.Note: The UV index of 6 in September translates into these instructions:
Stick with precautions and abide by sun safety procedures. Evading sunburn is essential. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
