Spring and autumn usually offer comfortable walking weather, while summer is humid and winter can be sharply cold.
Choose a season by what you want to do
Spring and autumn suit long neighborhood walks, palace grounds and outdoor viewpoints. Summer works better for travelers comfortable with humidity and rain interruptions, while winter rewards a plan that alternates exposed sights with indoor stops.
How the four seasons change a Seoul trip
Early spring can still feel wintry, and late autumn cools quickly after sunset. Summer heat is amplified on paved streets; winter wind is most noticeable along the Han River and at open viewpoints.
Crowds, daylight and reservations
Public holidays, festivals and blossom or foliage weekends can matter as much as temperature. Check the calendar for your dates, reserve any must-do ticketed activity, and leave flexible time around weather-dependent stops.
Use today’s evidence
Open the Seoul weather page for the latest observation, then use a Seoul live camera for a limited visual check of the specific area shown. A single camera cannot represent the whole city.
Before you act
- Match two priority activities to the season.
- Check Korean public holidays for the exact dates.
- Keep one indoor option near each outdoor cluster.

Is winter a bad time to visit Seoul?
No. It needs warmer clothing and shorter outdoor blocks, but markets, museums, cafés and rail-based day trips remain practical.
