Weather in August
Temperature
Macomb experiences a minor change to a still tropical 86.5°F (30.3°C) in average high-temperature during August, closely reflecting July. Nighttime temperature in Macomb lowers to an average of 66°F (18.9°C) in August.Heat index
The heat index in August is appraised at a fiery hot 98.6°F (37°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Resist overexposure. Safeguarding from solar damage is indispensable. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
