Decker's daily high temperature significantly diverges from the consistently recorded temperature low averaging a refreshing 60.4°F (15.8°C) in August.Heat index
August's mean heat index is estimated at 82.4°F (28°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature 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.

Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
