Weather in August

August, the last month of the summer in Highland Beach, is another tropical month, with temperature in the range of an average low of 81.5°F (27.5°C) and an average high of 87.1°F (30.6°C).

Temperature

August is the warmest month, exhibiting average temperatures of 87.1°F (30.6°C) at the peak and 81.5°F (27.5°C) at the base.

Heat index

August's average heat index is calculated to be a torrid 98.6°F (37°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
Remember that heat index calculations are made for conditions in the shade with light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. 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.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
