About Jeju Jungmun
Jeju Jungmun is the premier, highly accessible beach break located on the southern coast of Jeju Island, South Korea. The bathymetry consists of a gently sloping expanse of compacted sand nestled between prominent volcanic cliffs. Facing south, the beach captures moderate southerly wind swells and heavily diffracted Pacific typhoon groundswells during the summer months. A northerly offshore wind is required to structure the frequently chaotic sea state into rideable peaks. Because the wave energy is heavily attenuated and breaks over a very gentle sandy slope, the waves are typically soft, slow, and crumbly. This makes Jeju Jungmun an exceptionally safe and forgiving environment for beginner surfers. It provides consistent, low-power whitewater and highly manageable green faces, perfect for learning fundamental skills without the hazards of strong rip currents or steep drops found at exposed coastal reefs.

How often is this page updated?
Current conditions refresh every 6 hours when the cron runs. Hourly data updates every 30 minutes. The 7-day forecast, luck factor, and packing notes are all pre-computed at the same time.
What is the luck factor?
We compare the 7-day forecast to the last 5 years of marine data for the same week at Jeju Jungmun. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical late April.
How is 'best session' picked?
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.
Where does the data come from?
Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions).
Does the score capture local knowledge?
Honestly, no. Every break has tide windows, swell directions and reef contours that a global model cannot see. Treat the score as a starting point, then check a local cam.
