Honest weather data, packing guides, and gear advice for the destinations Singaporeans actually go to in Korea. Updated for the 2026 season.
Korea is colder, drier and windier than most Singaporeans expect. Seoul in December averages a daytime high of 3°C and a nighttime low of −5°C — and that's a "warm" winter day. January is harsher. The wind off the Han River is the part nobody warns you about.
The trips Singaporeans tend to make: a December long weekend in Seoul (Myeongdong, palaces, K-drama filming locations), a Pyeongchang ski week, a Jeju winter break (mild, but coastal-cold), and the increasingly popular cherry-blossom spring shoulder season — which is still cold enough that you'll need real layers.
