Weather in August
Temperature
Powell's average high-temperature in August is a still hot 87.1°F (30.6°C), marking an insignificant difference from the 88°F (31.1°C) of July. During the month of August, an average low-temperature of 68°F (20°C) is recorded.Heat index
For August, the heat index is calculated to be a very hot 100.4°F (38°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
