Is October’s Korea-Japan cruise line cold?

Cold.

On the Korea-Japan cruise ship in October, the wind was strong at sea and the outdoor temperature was low. The indoor temperature on the ship will be maintained at a constant temperature of about 25 degrees, so wear thicker clothing to cope with the cold weather. Thin blankets will be provided on board to ensure your comfort, and it is best to wear warm clothing suitable for outdoor conditions. Stay warm and comfortable during your cruise.
