Weather in September
Temperature
With the onset of September, a modest change to a still tropical 87.6°F (30.9°C) from August's 91.6°F (33.1°C) is noted in high-temperature. In Ruby, the September nights cool down to an average low of 68.5°F (20.3°C).Heat index
In September, the heat index is appraised at a blistering 104°F (40°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
