The Lowdown
Alright surfer, Rusty here with the lowdown on 38 Line. We’re starting off pretty flat and messy. First up, Saturday the 29th of August, there’s some small 3ft ESE swell with weak energy (58). The water is sitting at 80°, which is much warmer than average for late August. It’s surfable but very ordinary with a cross-off breeze.
Sunday the 30th of August has the best wind of that first week – glassy conditions in the morning with a light NNE breeze. The swell is tiny though, only about 3ft from the NE, with a short 6-second period. Energy picks up just a bit (119).
From Monday the 31st of August all the way through to Saturday the 6th of September, it’s a total blank. Just poor surf and tiny, weak swell. There’s a blip on Thursday the 3rd of September with 4ft NE swell in the morning, but it’s raining with a strong onshore wind, chopping it up. The energy hits 168 then 173 in the afternoon, but it’s just poor.
Monday the 7th of September afternoon is where it finally turns. We’ve got 6ft ESE swell with offshore NNW winds, and the energy jumps to 346. It says expect good surf conditions. That’s the real start of the action.
Now, Tuesday the 8th of September morning is a monster for experts only. It’s glassy, no wind, with a massive 10ft north swell at 9 seconds. The energy is huge at 1720, but the forecast says it’s too big for this break. That’s a heavy day. The afternoon is also 10ft but gets a touch of onshore breeze.
If you can be patient, Wednesday the 9th of September morning is the one. It’s glassy, with a clean 7ft NE swell at 10 seconds, and energy of 820. That’s very, very good surf. Just a beautiful, clean setup.
Thursday the 10th of September is another giant day – 10ft NNE groundswell at an 11-second period. The energy is off the charts at 3951, but it’s just too big for 38 Line again. Expert-only.
The second week fades. The best of that late run is Friday the 11th of September morning, with 7ft NE swell (10 seconds, 800 energy) and clean cross-off winds. After that, it’s back to small and poor through the 13th.
For my money, the absolute standout for most of us is Wednesday the 9th of September morning. Clean glass, a solid 7ft NE swell, and good energy. That’s the day to be in the water.
Rusty.

Information about the 38 Line Surf forecast
The above surf forecast table for 38 Line provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 38 Line can be found by selecting the local surf guide option on the grey menu. Our 38 Line surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (38 Line) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for 38 Line may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
38 Line is 18 km (11 miles) from the city of Sokcho. If you plan a holiday in South Korea, look for hotels and other accommodation in Sokcho. Sokcho has rooms for a wide range of budgets as well as car hire and transport links.
