SEOUL + BUSAN · OCTOBER
Seoul and Busan weather in October
A Seoul–Busan trip crosses two different city climates. Pack for the cooler part of the itinerary and use removable layers for warmer afternoons or the milder southern coast.Have travel dates already?Check recent observed weather patterns and confirmed official events for Seoul, Busan or Jeju.
Check my travel dates →The practical difference
Busan's coastal setting can feel milder but windier, while Seoul can have a stronger cool-down after sunset. The exact difference changes by date, so compare both cities for the same travel window instead of using two unrelated monthly averages.
One packing list for both cities
Use breathable base layers, long trousers, walking shoes and one jacket that handles wind. Add a warmer mid-layer if Seoul evenings fall below your comfort range, and keep a compact umbrella rather than packing separate wardrobes.
Plan by travel week
For a trip longer than seven days, the planner divides recent observed patterns into weekly sections. This helps show a seasonal change that one full-trip average could hide.
