Understanding Seoul Weather in January
The Seoul weather in January is known as the coldest time of the year. Historically, the average high temperature in early January is around 0.4°C (32.7°F), while the average low stays near -7.9°C (17.8°F). By late January, temperatures dip further, reaching a seasonal low of -8.8°C (16.2°F) around January 23rd.
Beyond the cold, January is incredibly dry. Daily precipitation ranges from a mere 0.4 mm to 3.3 mm. Humidity levels fluctuate between 61% and 69%, dropping to their lowest (65%) toward the end of the month. This combination of sub-zero temperatures and low humidity can be very taxing on your skin.
Real Survival & Style Guide for January
Navigate the freezing Seoul streets with these essential tips:
- Layering is Mandatory: Early to mid-January sees morning lows frequently hitting -10°C. A heavy long padding coat, thermal base layers, gloves, and scarves are non-negotiable.
- Snow & Slippery Roads: While January is dry, occasional snow or rain is expected, especially around January 10th. Be cautious of icy, slippery roads after a snowfall.
- Wind Chill Factor: Strong winds from the northwest can make the “feels like” temperature significantly lower than the actual reading.
