Weather in September
The first month of the autumn, September, is still a tropical month in New Boston, Texas, with an average temperature varying between 66.7°F (19.3°C) and 88.2°F (31.2°C).Temperature
September is marked by a subtle drop in average high-temperatures, transitioning from a hot 94.3°F (34.6°C) in August to a still tropical 88.2°F (31.2°C). The low-temperature average for New Boston during September stands at an enjoyable 66.7°F (19.3°C).Heat index
For most parts of September, the heat index is computed to be a fiery hot 100.4°F (38°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Fend off overexposure. Sun protection is vital. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears. Stay alert! Snow's reflective properties can almost double the UV radiation from the Sun.
