Jeju in November: Weather, Hallasan Foliage & What to Wear

November in Jeju is mild for late autumn but rarely calm. Wind, showers, and short days shape a trip more than the average temperature does.

Hallasan runs on a colder clock than the coast. The sections below keep typical climate, the current park rules, and this year's foliage forecast apart, so you can tell which is which.

Quick answer

Is November a good month to visit Jeju?

It suits walking, coastal drives, and quieter sightseeing without summer heat. It is a weaker month if your plan depends on swimming, a guaranteed clear summit view, or a red-maple display.

Weather here can change within a day, so build a plan that survives a wet or windy morning. The 3-day outline near the end of this guide is built that way.

Typical November weather in Jeju

These figures are 30-year climate normals (1991 to 2020) from the Korea Meteorological Administration, rounded. They describe a typical November, not the forecast for your dates.

Seogwipo is a little warmer than Jeju City and gets more rain in total, though on fewer days. Which base suits you depends more on your route than on these gaps, and the where to stay in Jeju guide compares the two areas.

Averages hide the spread. A sunny afternoon in a sheltered spot can feel mild, while the same day on an exposed ridge or the north coast can feel much colder, so check the KMA forecast before you go and again the evening before each outing.

Early versus late November

There is no sharp switch, and the exact dates shift each year. The pattern below is a general tendency, not a calendar.

If color matters most to you, lean early. If a quieter, cooler trip suits you, late November works as long as you accept less foliage.

Wind and rain in Jeju in November

Wind is the factor most visitors underestimate. It makes a cool day feel colder, and it hits hardest on coastal paths, oreum (volcanic cone) summits, and open viewpoints.

Rain usually arrives as showers rather than long soakers, but it can turn a walking day into an indoor one. Strong wind or rough seas can also cancel boats to the smaller islands and, on some days, affect flights. Keep the final day of your trip flexible and check the airline and ferry operator before you travel.

Wet lava rock and boardwalks are slippery. Shoes with real grip matter more than a stylish pair.

Hallasan in November

Hallasan rises to 1,947 m, so the mountain can be several degrees colder than the coast. Air temperature typically falls with height, and wind adds to it. On a mild coastal day the upper mountain can sit near freezing, and the summit area can be colder still.

Which trails to consider

The summit (Baengnokdam crater) is reached only by the Seongpanak and Gwaneumsa trails, and both need a reservation. Eorimok, Yeongsil, Donnaeko, Seokgulam, and Eoseungsaengak do not need one for their own routes, but they do not reach the summit. The island overview covers this in more detail in the Jeju travel guide.

The Gwaneumsa trail's upper section, between Samgakbong and the summit, was closed for rockfall-barrier works from 1 August 2026 and reopened on 24 September 2026, according to the park's notices. Check the notice board for any new works before you plan around that trail.

Reservations and ID

The park's reservation system releases each month's slots at 09:00 on the first weekday of the previous month, according to its notice. A queue can form on release day and popular dates can fill, so decide early.

Bring photo ID. The park checks hikers' identity against the reservation QR code at the entrance, and its June 2026 notice says a mismatch can mean being refused entry and a one-year entry ban.

Winter entry times

The park applies a winter schedule from 1 October 2026 to 31 March 2027, according to Korean news reports of the park's announcement. Entry starts at 05:00. The last entry at Seongpanak and Gwaneumsa, the two summit trails, is 11:30. Eorimok and Yeongsil close entry at 12:00, and Donnaeko at 10:00.

There are turnaround times too: hikers reportedly must start down from the summit's east ridge by 13:30. That is the shape of the rule, not a substitute for the park's own table, so confirm the current times on the reservation site before you book.

Getting to Seongpanak

The Seongpanak parking lot is small and fills early, and the park's notice recommends public transport. It also lists a free overflow lot on the 5.16 Road near Jeju International University. Bus 281 between the Jeju and Seogwipo bus terminals passes the trailhead, and roadside parking is subject to enforcement.

Cold, snow, and gear

Snow or ice can appear on the upper mountain in some Novembers and not in others. Do not assume either. Winter hiking notices in the news reports advise warm outer layers, spare clothing, hot water, emergency food, and crampons.

Carry crampons or another traction device if the park's current notice or same-day trail report mentions snow or ice on your route. If it does not, decide with the conditions at the trailhead, and turning back is always an acceptable choice.

Check the trail on the same day

Trail status can change with weather, and a section can be restricted at short notice. Look at the Hallasan National Park reservation site's notices on the morning you hike, and follow staff instructions at the entrance. In an emergency, call 119.

Can you see autumn foliage on Hallasan in November?

Sometimes, and only in part. Color on a tall mountain generally moves downhill as autumn goes on, so by November the higher slopes are usually past their color while the lower and middle slopes may still have some.

For 2026, the Korea Forest Service's foliage forecast map, announced on 22 September and reported in Korean media, gives 6 November as the reference date for Hallasan. The agency defines peak as the point when about half the leaves on a mountain have changed color. It is a forecast built from past patterns, so it can move with the weather.

Treat that date as a rough guide, not a promise. Elevation, slope, and species change what you see, and much of Jeju's forest is evergreen, so color often comes in patches rather than as a solid wall of red. Check the current forecast again in the week before you fly.

If Hallasan color is not showing on your dates, lowland stops can fill the gap. Silver grass fields such as Sangumburi are strongest earlier in autumn and may be fading by November, so look at recent photos or reports before you build a day around them. For a nationwide view of timing, see the Korea autumn foliage guide.

What to wear in Jeju in November

Think in layers you can add or remove: a base layer, a warm mid-layer, and a windproof, water-resistant shell. The shell is the piece that earns its place on Jeju.

Coast and city days

A light knit or fleece under a windproof jacket covers most days, with a scarf or thin gloves for evenings. Closed shoes with grip work better than sandals or canvas sneakers. An umbrella is hard to use in strong wind, so a hood is more reliable.

Windy attractions

Oreum summits, coastal paths, and lighthouse viewpoints feel colder than the forecast temperature. Add a hat that stays on and wind-resistant gloves before you climb, and dress for a few degrees colder than the forecast.

Hallasan hiking

Wear moisture-wicking layers, not cotton, with an insulating mid-layer and a waterproof shell. Add a warm hat and gloves, sturdy hiking shoes or boots with good grip, and a spare layer in your pack. Bring crampons if conditions call for them, as described above.

Early versus late November

For early November, one warm layer under a shell is usually enough on the coast. For late November, add a heavier mid-layer, a warmer hat, and gloves for morning and evening outings.

Packing checklist

• Windproof, water-resistant jacket with a hood
• One or two warm mid-layers (fleece or light down)
• Quick-drying base layers for hiking days
• Comfortable shoes with real grip; hiking shoes if you plan any trail
• Warm hat and gloves
• Compact day pack with water, snacks, and a spare layer
• Sunglasses and sunscreen for clear, bright days
• Power bank and an offline copy of your bookings
• Photo ID (checked at Hallasan entrances)
• Crampons only if the park's current notice or trail report calls for them

Common mistakes

1. Packing only for the coast's average temperature and skipping a shell
2. Treating a forecast peak-foliage date as a promise
3. Planning a Hallasan summit hike without a reservation, or arriving after the entry cutoff
4. Wearing smooth-soled shoes on wet lava rock and boardwalks
5. Filling every hour with outdoor stops and leaving no wet-weather plan
6. Driving mountain roads late in the day without checking conditions
7. Relying on climate averages instead of the KMA forecast for your dates

What to do in Jeju in November

Walk part of an Olle route

The Jeju Olle trails follow coastal and inland routes and can be walked in sections. Pick a short stretch, expect wind on open shoreline, and check the Olle Foundation's site for route details and any temporary detours.

Climb an oreum on a clear morning

Oreum climbs are short and rewarding when the air is clear. Choose a low-wind morning, and be ready to skip the summit if cloud or gusts move in.

Look for mandarin season

Jeju's mandarins are typically harvested from autumn into early winter, according to provincial agricultural guidance, so you will often see orchards in fruit. Timing varies by variety and year. Orchards are private property, so pick only at a farm that welcomes visitors, and never take fruit from roadside trees.

Camellias: keep expectations modest

Camellia is Jeju's winter flower, and the main show tends to come later in winter. Do not plan a November trip around it, and check the garden's own site for current bloom information.

Coast and beach walks

Beaches are for walking in November rather than swimming. The Jeju beaches guide covers the main beaches.

Driving and daylight

Daylight is short in November, and it shortens as the month goes on. Look up sunrise and sunset for your exact dates from the Korea Astronomy and Space Science Institute rather than relying on a single time.

Plan to finish outdoor stops with daylight to spare, especially in mountain areas. Roads that cross the Hallasan area can be affected by fog, wind, or snow, so check conditions before you set out. The Jeju car rental guide covers permits and pickup.

Who should choose November

A good fit if you:

• Like walking, oreum climbs, and coastal drives more than swimming
• Want cool, comfortable sightseeing days without summer heat
• Are flexible enough to swap an outdoor day for an indoor one
• Want to see the island in fruit and late-autumn color rather than peak foliage

Look at another month if you:

• Need warm sea days or a beach-centered trip
• Are set on peak red foliage or a guaranteed clear summit
• Have a fixed schedule that leaves no room for wind or rain

For a colder-season comparison, see the Korea winter travel guide.

A flexible 3-day outline

This is a pattern, not a fixed schedule. Swap days depending on the forecast.

• Day 1: Coast and city. Pick a coastal drive or one Olle stretch, with a museum or covered market as your fallback if it rains.
• Day 2: Hallasan or an easier mountain day. If you have a summit reservation and the trail is open, go early. If not, choose a shorter trail without a summit reservation, or an oreum.
• Day 3: Flex day. Use it for whichever plan the weather blocked, and leave the afternoon open before your flight.

Frequently asked questions

Is November a good time to visit Jeju?

Yes for walking, driving, and quieter sightseeing, if you accept cool, breezy weather and shorter days. It is a weaker choice for swimming or a guaranteed foliage display.

How cold is Jeju in November?

Typical daily highs are about 16 °C in Jeju City and 18 °C in Seogwipo, with lows near 10 to 11 °C (KMA 1991 to 2020 normals). Wind can make it feel colder, and Hallasan is colder still.

Is Jeju City or Seogwipo warmer in November?

Seogwipo is a little warmer in the KMA normals and gets more rain in total. Either can be windy, so a shell jacket matters in both.

Does it rain a lot in Jeju in November?

Rainfall is moderate in the normals, about 70 mm in Jeju City and 86 mm in Seogwipo. Showers are common enough that you should plan an indoor backup.

Can I see autumn foliage on Hallasan in November?

Possibly on the lower and middle slopes, less so higher up. The Forest Service's 2026 forecast gives 6 November as the reference date, but it is a forecast and can move.

Can I hike Hallasan in November?

Yes, if the trail is open, but the summit trails need a reservation and have entry cutoffs. Check the park's same-day notices before you go.

Do I need crampons for Hallasan in November?

Only if the current notice or trail report mentions snow or ice on your route. Conditions vary from year to year, so do not assume either way.

What should I wear for Hallasan in November?

Moisture-wicking layers, an insulating mid-layer, a waterproof shell, a warm hat and gloves, and grippy hiking shoes. Add crampons if conditions call for them.

What should I pack for Jeju in November?

A windproof jacket, warm mid-layers, shoes with grip, a hat and gloves, a day pack, and photo ID. The checklist above has the full list.

Is it too cold to swim in November?

For most visitors, yes. Treat beaches as walking spots and check local conditions before entering the water.

Is wind a problem in November?

It can be. Wind makes the weather feel colder and can disrupt boats and, on some days, flights, so keep your last day flexible.

Is it worth renting a car in November?

A car makes it easier to reach oreum, coastal stops, and trailheads, but short daylight and mountain-road conditions call for earlier starts. See the car rental guide for permits.

When should I book the Hallasan reservation?

Each month's slots release at 09:00 on the first weekday of the previous month, so plan ahead and confirm the current rules on the reservation site.

Check before you go

• KMA forecast and any wind or rain warnings near your dates
• The Hallasan reservation site's notices for trail closures and entry times
• The Forest Service's current foliage map if color is your priority
• Airline and ferry notices for wind-related changes
• Sunrise and sunset times for each of your days
