South Korea Weather in October 2025: Travel Tips for First-Timers

October exemplifies autumn perfection in South Korea. Not only will you be greeted to stunning fall landscapes during the month, but also be accompanied with endless hours of sunshine and comfortable temperatures. October temperatures in South Korea range from highs of 22°C (72°F) and lows of 7°C (45°F).

The stunning weather and breathtaking fall views do, however, attract tourists from all over the country (and the world!). So, be ready to run into plenty of crowds if you're traveling to South Korea in October. This is especially true in popular hotspots like Nami Island. The increase in tourism also results in accommodation and airfare prices going up.

It'll be important to plan for both warm and cool weather conditions for October in South Korea. Although the afternoons, especially during the first part of the month, can be warm, the early hours of the mornings and the late hours of the evenings will certainly be chilly. The second half of October will be cool throughout. Remember to pack plenty of sweaters and cardigans, a windbreaker, some hoodies and fleece jackets, warm socks, scarves, warm dresses, boots, dress shoes, and a pair of comfortable walking shoes.
