Weather in September
Temperature
Slater's transition into September involves a gentle shift in temperature, receding from a fiery hot 95.5°F (35.3°C) in August to a tropical 87.6°F (30.9°C). Throughout September, Slater witnesses a nighttime temperature average of 70.7°F (21.5°C).Heat index
For most parts of September, the heat index is calculated to be a torrid 96.8°F (36°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Records show heat index calculations are tailored for shaded regions and mild winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Sunshine

In September, the average daily maximum UV index is 6. A UV Index estimate of 6 to 7 represents a high health hazard from unprotected exposure to Sun's UV rays for ordinary individuals.Note: In September, a regular UV index of 6 translates into these guidelines:
Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
