August, the last month of the summer in Athens, is another hot month, with an average temperature fluctuating between 64.9°F (18.3°C) and 86.9°F (30.5°C).

Temperature

Welcoming August, Athens notes an average high-temperature of a still tropical 86.9°F (30.5°C), nearly consistent with July's 87.6°F (30.9°C). Athens documents a significant temperature variance in August, with the mean nighttime lows settling at a comfortable 64.9°F (18.3°C).

Heat index

August's average heat index is calculated to be a sweltering 100.4°F (38°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
