Weather in August
Temperature
In Stuart, Florida, August records the highest average temperatures, peaking at 87.1°F (30.6°C) and reaching a low of 79.3°F (26.3°C).Heat index
In August, the heat index is estimated at a very hot 102.2°F (39°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Know that the heat index computations account for shaded terrains and slight winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Deflect overexposure. Sun protection is a necessity. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized. Notice! Sand and water reflections contribute to a stronger UV exposure.
