August, the last month of the summer in Stewart, is also a hot month, with an average temperature ranging between min 67.3°F (19.6°C) and max 87.8°F (31°C).

Temperature

The onset of August notes an average high-temperature of a still tropical 87.8°F (31°C), subtly shifted from July's 88.9°F (31.6°C). Stewart's average low-temperature for the month of August records at a comfortable 67.3°F (19.6°C).

Heat index

For August, the heat index is computed to be a fiery hot 102.2°F (39°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
