Seoul has four real seasons plus monsoon and dust weeks. Here's what to actually pack in a carry-on for each, plus how to dress for each district's vibe.
Cherry blossom in early April. Cool mornings (8°C), warm afternoons (18°C). The trickiest packing season, bring layers.
Humid + hot (28-32°C peak). July is monsoon: ~3 weeks of solid rain. UV is intense. AC is everywhere, slightly chilly indoors.
The best season, hands down. Crisp dry days (20°C), foliage peak in late Oct. Locals' favorite. Visually photogenic.
Cold and dry (-5 to 5°C). Wind-chill makes it feel colder. Snow is occasional. Heating is everywhere, dress in layers you can shed.
Match the energy, your sharper outfits get worn here.
Be casual. Sneakers + interesting tee. No need to overdress.
Brand-aware streetwear. Korean labels, neutral palette.
Comfortable shoes (1+ km of walking). Hanbok rental gets you free palace entry.
Anything goes. Most permissive dress code in Seoul.
Smart casual is the safest. No flip-flops.
