The average temperature hovers around 30°F to 37°F (about -1°C to 3°C). At the beginning of December, it might be a bit warmer, around 41°F (5.3°C), but as the month goes on, it gets colder and colder, dropping to about 36°F (2.4°C) by the end of December.

So, really, warm clothes are a must-have if you’re visiting during this time. You’ll want to be prepared to stay toasty while exploring all the cool things Seoul has to offer!

Rainfall in December: What to Expect

Now, about rain! Even in winter, sometimes it rains, you know? In December, Seoul usually has about 3 to 8 rainy days, with a total rainfall of about 40mm for the whole month.

At the beginning of December, there isn’t much rain. But as we get closer to the middle of the month, the chances of rain go up. For instance, around December 23rd, there’s a good chance of moderate rain, and even on December 24th and 31st, there could be some scattered showers.

So, it’s a good idea to always carry a small umbrella, just in case! And if you have a waterproof jacket, that would be super helpful too. This way, you won’t let a little rain spoil your fun!

Snow in Seoul: Will it Be a White December?

What about snow? For many of us, winter in Seoul means dreaming of snow! Typically, December sees about 7 snowy days in Seoul. But for December 2025, predictions say there might not be any snow until the end of the month.

However, weather forecasts can change, right? As of now, within a 14-day forecast, there’s a chance of one snowy day with a small amount of snow, around 0.1cm. Specifically, a light snow shower is expected around December 16th, and more snow (about 1.1cm) could fall on December 21st. So, maybe we’ll get a little bit of a white winter after all!
