August comes burdensome with the continuation of high heat, intense humidity, and frequent rainfall. The frequency of rainfall reduces slightly compared to
July while the temperatures slightly increase. High relative humidity becomes the norm during this month, increasing the discomfort in the city. On the plus side, the number of hours of daylight begins to decline at a slow pace. The sea, maintaining its warm temperatures, continues to be a coastal city's solace.
Temperature
In
Incheon, the peak average temperatures are observed in August, with a high of 29°C (84.2°F) and a low of 22.4°C (72.3°F).
Heat index
The heat index value during August is computed to be a very hot 35°C (95°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
Humidity
The average relative humidity in August is 79.1%.
Rainfall
In August, the rain falls for 12.5 days. Throughout August, 286mm (11.26") of precipitation is accumulated. Throughout the year, there are 101.9 rainfall days, and 1235mm (48.62") of precipitation is accumulated.
Sea temperature
The month with the warmest seawater is August, with an average sea temperature of 23.4°C (74.1°F).
Note: While a person's sensitivity to cold is personal, factors like sunshine, wind, and the temperature can influence their comfort in 23.4°C (74.1°F) waters. Olympians, for perspective, swim in waters between 25°C (77°F) and 28°C (82.4°F).
