Electrical Plug and Voltage

The standard voltage in Korea is 220 volts/60 hertz. The outlet has two round holds and is the same type used in countries such as France, Germany, Greece, and Turkey. If your electrical device does not support 220 volts, you must bring a multi-voltage travel adapter. You may purchase one at a duty-free shop or a convenience store at Incheon International Airport or at the stationery shop on POSTECH campus.


The Republic of Korea has a temperate climate with four distinct seasons: cold winters, hot summers, and sunny and generally dry transition seasons – spring and fall. The annual mean temperature ranges from 10°C to 16°C. August is the hottest month (mean temperature 23-27°C), and January is the coldest month (mean temperature -6-7°C).

Annual precipitation ranges from 1,000 mm to 1,800 mm. More than half of the total rainfall is concentrated in the summer season, especially in late June. The relative humidity is the highest in July (80-90%) and the lowest in January and April (30-50%).
