Weather in September
Temperature
Garvin's progression into September involves a minor drop in the average high-temperature, slightly receding from 93.7°F (34.3°C) in August to a still hot 87.3°F (30.7°C). A striking difference from the daytime highs is registered during September nights, with an average temperature of 65.7°F (18.7°C).Heat index
Throughout September, the heat index is evaluated at a sweltering 96.8°F (36°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. 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 remain especially vital for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Sunshine

The average daily maximum UV index in September is 6. A UV Index value of 6 to 7 symbolizes a high health risk from unsafe exposure to UV radiation for the average person.Note: A daily maximum UV index of 6 in September translates into the following instructions:
Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
