Rain days are the days with at least 1 mm of rain, as a weather station counts them.

Weather read at Jeju City: ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

How busy it gets

Busiest in May and August; quietest in December and January.

Then and now

Jeju's May days now average 22.0°C, 2.3°C warmer than in 1981–1990. 7 of 12 months are clearly warmer.

Getting there

How far Jeju is, and what it costs, depends on where you set off from — the months above do not.

Before you go

Type C and F plugs at 220 V. Drives on the right. The currency is the Won. No UK Foreign Office advice against travel. Everything for South Korea: cost of living, languages, emergency numbers and health.

Being there

On arrival

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.
Tipping — Not expected, including in taxis; some hotels and tourist restaurants add a 10% service charge.

Getting around Jeju

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.

Nothing in downtown Jeju is more than approximately 2 km from anywhere else so whilst not convenient, walking is quite feasible, and sometimes even faster than the bus. More on Wikivoyage

Help

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.

What Jeju is like

Jeju Island (제주도,濟州島 and formerly romanized as Cheju) is an island off the southern coast of South Korea in the Korea Strait. Korea's largest island and a popular vacation spot and honeymoon destination for Koreans and Chinese, it is crowded with tourists all-year round. The main town and capital is Jeju City. More on Wikivoyage

Worth seeing: Lava tubes and other volcanic sights. Jeju Volcanic Island and Lava Tubes is a UNESCO World Heritage site in the "nature" category. More on Wikivoyage
Worth doing: There are many hiking trails in the Hallasan National Park. Iho Tewoo Beach in Jeju City is close to Jeju Airport, and it is enough distance to ride a bicycle. More on Wikivoyage
Getting in: Jeju has implemented the Korean Electronic Travel Authorization (K-ETA) requirement for travelers from visa-waiver nations. More on Wikivoyage
Staying safe: While South Korea in general is remarkably safe, Jeju has the lowest crime rate in the country. More on Wikivoyage
