Weather in August

August, the last month of the summer in Gravel Junction, is another tropical month, with an average temperature varying between 92.8°F (33.8°C) and 71.1°F (21.7°C).

Temperature

During August, Gravel Junction observes a subtle ascent to a still tropical 92.8°F (33.8°C) from July's 93.2°F (34°C) in the average high-temperature. Throughout August nights, Gravel Junction reports a steady thermal contrast from the day, with an average low-temperature of 71.1°F (21.7°C).

Heat index

The average heat index in August is evaluated at a life-threatening hot 116.6°F (47°C). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', comes about by integrating the temperature readings with the humidity levels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
