Weather in September
Temperature
Transitioning into September, Violet records an average high-temperature of a still hot 86.2°F (30.1°C), almost identical to August's 89.2°F (31.8°C). Throughout the month of September, the nighttime temperature dips to an average of 76.6°F (24.8°C).Heat index
In September, the average heat index is appraised at a fiery hot 96.8°F (36°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Resist overexposure. Safeguarding from solar damage is indispensable. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
