A practical introduction to the country: seasons, payments, transport, everyday etiquette, and the small details that make a first visit easier.

QUICK ANSWER

South Korea is straightforward to explore when you prepare three things: mobile data, a transport card, and a backup way to pay. Cities are well connected, but the weather changes sharply by season and local digital services may work differently from the apps you use at home.

01

01 · CONTEXT

Four genuinely different seasons

Spring and fall are generally comfortable for walking. Summer is hot, humid, and overlaps with the rainy season; winter can be dry and intensely cold. Check the live forecast before packing rather than relying only on monthly averages.

  • March–May: light layers for changing temperatures
  • June–August: humidity, rain, and strong sun
  • September–November: mild days and cooler evenings
  • December–February: a warm coat, gloves, and suitable shoes

02 · MONEY

Cards are common, but carry a backup

The currency is the South Korean won (KRW). Cards are widely accepted, though a foreign card can fail at a particular machine or shop. Bring a second card and a little cash for markets, top-ups, or small businesses.

03 · DAILY LIFE

Data, maps, and simple etiquette

Arrange an eSIM, SIM, or Wi-Fi before leaving the airport. Naver Map and KakaoMap are often useful for local routes. Keep your voice low on public transport, let people exit first, and respect priority seats. You do not need to memorize every custom—observe and ask politely.

04 · SHOPPING

Souvenirs that travel well

Skincare, stationery, tea, small ceramics, and locally designed goods are practical choices. Compare prices and check airline rules for liquids. Tax-refund eligibility depends on the store and current conditions.
