Best Time Visit Seoul: I Regret Going in Summer
Visit Seoul in April, May, October, or November. These months give you 15-25°C weather, cherry blossoms or fall colors, and tolerable crowds. Summer (June-August) is a humid nightmare, and winter freezes your face off.
I learned this the hard way in July 2024. Stepped off the plane into what felt like a wet sauna, spent ₩50,000 on an emergency umbrella during a monsoon downpour, and watched my carefully planned street food tour turn into a sprint between air-conditioned cafes. Don't be me.
The Verdict: Seoul's Best and Worst Months
| Month | Weather | Crowds | Costs | Rating |
|---|---|---|---|---|
| April | 12-20°C, cherry blossoms | Medium | Mid | ★★★★★ |
| May | 17-25°C, perfect | Medium-High | Mid-High | ★★★★★ |
| June | 21-27°C, rain starts | Medium | Mid | ★★ |
| July | 24-30°C, monsoon hell | Low | Low | ★ |
| August | 25-31°C, humidity 80%+ | Low | Low | ★ |
| September | 20-27°C, typhoons | Medium | Mid | ★★★ |
| October | 12-21°C, fall colors | High | Mid-High | ★★★★★ |
| November | 5-13°C, crisp | Medium | Mid | ★★★★ |
| December | -2-6°C, Christmas vibes | Medium-High | Mid-High | ★★★ |
| Jan-Feb | -6-3°C, brutal cold | Low | Low | ★★ |
| March | 4-12°C, warming up | Medium | Mid | ★★★ |
The best time to visit Seoul is April-May or October-November. These shoulder seasons give you comfortable weather, manageable crowds, and reasonable hotel prices. Everything else is a compromise.
💡 Pro tip: Book Seoul accommodations 60-90 days out during peak months (April, October). I've seen hotel prices double when I waited until 30 days before my October trip.

Spring in Seoul (March-May): Peak Season for a Reason
March: The Awkward Transition
Temperature: 4-12°C | Rain: 7 days | Crowds: Medium
March is Seoul shaking off winter. Some days you'll walk around in a light jacket; others you'll wonder why you didn't pack that down coat.
The real action doesn't start until late March when plum blossoms show up around Gyeongbokgung Palace. But honestly? March is better for budget hunters than cherry blossom chasers.
What I liked: Hotel prices 20-30% cheaper than April. Fewer tourists at palaces. You can actually get a table at that seoul korean bbq spot in Mapo without a 2-hour wait.
What sucked: Still cold enough that outdoor exploring gets old fast. Yellow dust storms from China blow through (check Korea Meteorological Administration air quality forecasts).
| Item | Cost (March) | Cost (April) |
|---|---|---|
| Hotel (mid-range) | ₩80,000-120,000/night | ₩120,000-180,000/night |
| Flight (LAX-ICN) | $650-800 RT | $850-1,100 RT |
| Tourist density | 60% capacity | 95% capacity |
April: Cherry Blossom Chaos
Temperature: 12-20°C | Rain: 8 days | Crowds: High
The best time visit Seoul hits its first peak in April. Cherry blossoms explode around April 5-15 (varies yearly), and the entire city loses its mind.
Yeouido Spring Flower Festival draws 2+ million people. Seokchon Lake turns into an Instagram battlefield. But here's the thing—it's worth the crowds.

Just maybe don't do it in July.
