Weather in August
Temperature
The transition from July to August brings an average high-temperature of a still moderately hot 82.8°F (28.2°C), barely different from July's 83.8°F (28.8°C). Despite drastic daytime highs, Mammoth logs an average low-temperature reading of 59.4°F (15.2°C) throughout August.Heat index
For most parts of August, the heat index is computed to be a tropical 89.6°F (32°C). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. 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 especially crucial for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.

Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
