Weather in August
Temperature
With August's arrival, Macomb's weather records an average high-temperature of a still hot 86.5°F (30.3°C), marking little difference from July's 88°F (31.1°C). Macomb records an average nighttime low of 66°F (18.9°C) in August.Heat index
For August, the heat index is appraised at a sweltering 98.6°F (37°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. 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. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
