Weather in September
Temperature
On the advent of September, Ruby's average high-temperature exhibits a minor adjustment to a warm 83.8°F (28.8°C) from August's 88.3°F (31.3°C). In Ruby, September nights cool down to an average of 65.3°F (18.5°C).Heat index
The heat index value during September is calculated to be 84.2°F (29°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. 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. Mark this! Snow reflection can nearly double the UV radiation intensity from the Sun.
