Jeju Island in October

Spring arrives early on Jeju, with cherry blossoms blooming in late March. April brings perfect hiking weather – warm days, cool nights, and minimal rain. The famous canola flower fields peak in early April, creating yellow carpets across the island. Hotel prices stay reasonable, and crowds remain manageable. May extends the spring weather but marks the beginning of tourist season. Temperatures hover around 20°C, perfect for outdoor activities. This is your last chance for reasonable accommodation prices before summer peaks. Autumn, particularly September through November, rivals spring for ideal conditions. September can still feel summery, but October brings crisp air perfect for hiking Hallasan mountain. November offers the year's most dramatic sunsets and the lowest hotel rates. Winter brings strong winds and occasional snow on Hallasan peak, but temperatures rarely drop below freezing at sea level. December through February sees the fewest tourists and cheapest flights. Many outdoor attractions close or operate limited hours, but hot springs and indoor markets provide plenty to do.
