August weather forecast
Crossville, AL

August in Crossville continues the trend of high temperatures, but with a slight dip when compared to the preceding month. The scorching temperatures alleviate just enough to distinguish itself from the peak of summer in July. Sunshine isn't as abundant as in June, but still significantly high, making sun protection crucial for any outdoor activities. August however, also marks the beginning of a decline in both temperature and daylight hours, hinting at the approaching end of summer. Despite this, August remains firmly within the grip of summer, delivering high temperatures, abundant sunshine, and relatively low wind speeds.

Temperature

Crossville's average high-temperature in August is a still hot 87.4°F (30.8°C), marking an insignificant difference from the 88.3°F (31.3°C) of July. Crossville, in August, witnesses an average low-temperature of 67.8°F (19.9°C).

Heat index

The heat index for August is calculated to be a sweltering 102.2°F (39°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
Note that heat index values are valued for light wind and location in the shade. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high 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.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
