Wonju. Longer daylight hours cater to a variety of outdoor activities as the sun generously beams down on the city. However, this month also ushers in the heaviest rainfall of the year, marking a typical monsoon season in Korea. The highest rainfall of 362mm (14.25") marks July as the rainiest month, contributing to high humidity levels. As the heat and superb rainfall sweep across the city, July provides a unique charm in spite of the humidity and rain.
Temperature
Shifting into July, Wonju records an average high-temperature of a still moderately hot 29.3°C (84.7°F), presenting minor fluctuations compared to the previous month. July brings with it a nighttime average temperature of 20.8°C (69.4°F) in Wonju.
Heat index
For July, the heat index is calculated to be a fiery hot 35°C (95°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Note that heat index values are valued for light wind and location in the shade. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
