Weather in August
Temperature
In Denison, the highest average temperatures are observed in August, with a high of 93.9°F (34.4°C) and a low of 73.6°F (23.1°C).Heat index
In August, the average heat index is evaluated at a blisteringly hot 109.4°F (43°C). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.Consider that heat index readings are for situations in the shade and light wind. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
