Swimsuit for Busan in October
Verdict
Optional
A swimsuit is small — bring it if the hotel has a heated pool or spa.
Why
Busan in October averages highs of 69°F, lows of 56°F, 7 rainy days.
That climate makes a swimsuit a judgment call. A swimsuit is small — bring it if the hotel has a heated pool or spa.
