Weather in August
Temperature
A minimal variation is noted in Metcalf's average high-temperature at the onset of August, reaching a still warm 81.1°F (27.3°C) from July's 82.4°F (28°C). During August, Metcalf's temperature falls to a steady low-temperature average of 64°F (17.8°C).Heat index
In August, the average heat index is calculated to be a hot 87.8°F (31°C). With unrelenting exposure and activity, one might experience exhaustion, leading to potential heat cramps.Heat index's context suggests values are appropriate for shady areas and slight breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.

Take precautions. Light skin individuals may get burned in less than 30 minutes. Solar radiation is at its peak intensity during midday, so it's advisable to stay indoors or in the shade. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
