Weather in August
The last month of the summer, August, is another tropical month in Allison, Texas, with an average temperature fluctuating between 92.3°F (33.5°C) and 71.2°F (21.8°C).Temperature
August's climate shows a minor adjustment in average high-temperatures to a still hot 92.3°F (33.5°C) from July's 93.4°F (34.1°C). An average low-temperature of 71.2°F (21.8°C) is common during the nights of August.Heat index
For most parts of August, the heat index is evaluated at a very hot 98.6°F (37°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. 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 'apparent temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 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.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection.
