Weather in September
Temperature
A minimal variation is noted in Hines's average high-temperature at the onset of September, reaching a still tropical 87.1°F (30.6°C) from August's 89.8°F (32.1°C). Nighttime temperatures hover around an average low of 73°F (22.8°C) in September.Heat index
During September, the heat index is computed to be a very hot 102.2°F (39°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Note that heat index values are valued for light wind and location in the shade. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Sunshine
In Hines, the average sunshine in September is 8.8h.UV index
In September, the average daily maximum UV index is 6. A UV Index of 6 to 7 symbolizes a high threat to health from unprotected exposure to Sun's UV rays for the average person.Note: An average maximum UV index of 6 in September leads to these recommendations:
Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
