Climate Chart of Yongin, South Korea

Climate overview

Temperature

The coolest monthly mean is in January, at -2.3 °C, while the warmest is in August, at 25.3 °C. These are monthly mean temperatures, not daytime highs, so they describe the average conditions for each month rather than the temperatures a visitor should expect at a particular hour. Across the calendar-month means, the unweighted mean is 12.0 °C; it is not a day-weighted annual average.

Rain

Mean daily rainfall reaches its highest monthly level in July, at 9.15 mm/day, and its lowest in January, at 0.49 mm/day. The figures are daily averages, not monthly totals, and a lower average does not guarantee rain-free days or indicate how often rain falls. The unweighted mean across calendar-month averages is 3.24 mm/day, which provides a broad reference rather than a day-weighted yearly total.

Sunshine

Mean daily sunshine is highest in May, at 10.07 hours/day, and lowest in December, at 6.96 hours/day. These values describe average sunshine duration per day, not daylight length, and do not guarantee how sunny any individual day will be. The unweighted mean of the calendar-month averages is 8.37 hours/day.

Snow

The highest monthly mean daily snowfall is recorded in December, at 1.69 mm/day; the unweighted mean across calendar-month averages is 0.47 mm/day. These daily means do not establish how many days have snowfall, snow depth or snow cover, and cannot by themselves indicate skiing conditions.
