Each cell is that destination's own verdict for the month — sweet spot, ok or avoid — with its typical daily high, from the same ten years of climate readings its page is built from. A dot marks a busy month. The last row counts the sweet spots, and the best months are marked.

On arrival

Apps — Rides: Kakao T, k.ride, TADA, Uber. Maps: Kakao Map, Naver Map. Messages: KakaoTalk. Google Maps still gives no walking or driving directions in South Korea; use Naver Map or Kakao Map.
Paying — Visa and Mastercard are taken almost everywhere, even for a coffee, but phone wallets such as Apple Pay often fail. Carry some cash for the countryside; T-money also pays in convenience stores.
UPI, for visitors from India — Not accepted for paying here; bring a card that works abroad.
Getting around Seoul — T-money card on the subway, buses and taxis; buy and top up, usually with cash, at stations and convenience stores. A Climate Card pass covers 1 to 7 days. Foreign bank cards cannot be tapped yet.
Tipping — Not expected, including in taxis; some hotels and tourist restaurants add a 10% service charge.
Emergency — police 112 · ambulance and fire 119.
TravelCharika is not an emergency service: we cannot call for help or send anyone. Numbers can change; if one fails, ask someone local or your hotel.

Every verdict here is the destination's own: ten years of climate readings, the public holidays that crowd it, and what the flight costs. Nothing is said about South Korea as a whole that was not first measured at each place in it.
