What's the weather like in Busan by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Busan during Apr–Jun, Sep–Oct?
Cherry blossoms peak in late March to early April, earlier than Seoul. Pleasant temperatures with occasional rain.
Shoulder season (Mar, Jul–Aug, Nov) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Feb, Dec) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
