The Lowdown
Alright, Rusty here. Let's take a look at what we've got for 38 Line.
Right off the bat, I gotta be straight with you – this is a tough run. We're looking at a solid stretch of quiet, small surf to kick things off. There's almost nothing on the table for the first week or so, just a whole lot of flat, tiny dribble. From Thursday the 6th all the way through to the end of the following week, it's a major struggle. You'll be waiting a while.
Things finally start to look a bit more interesting around the second weekend. Saturday the 16th morning sees some energy building, with a 7 ft swell from the NE (combined energy of 620) but it's got a short period of 8 seconds and the wind is cross-off from the NNW, which will keep it clean. By Monday the 17th morning, we might actually have a little window. We've got a 6 ft NE swell, still that short 8-second period, but the wind is cross-off from the NNW again, leaving it clean. The combined energy is moderate at 369. It's not the best quality, but it's the best we've seen in a while. For an exposed break like this, a short-period NE swell with cross-off wind can sometimes offer a few workable ones.
The absolute standout here, if you can wait, is a much bigger pulse of energy. Around Wednesday the 12th and into Thursday the 13th, the combined energy jumps up to some serious numbers (532 to 1053), with swell heights hitting 7 ft to 8 ft from the NE. The period is still short, only 8 to 9 seconds, but the power is there. The catch is that the wind is mostly cross-onshore from the NNE or NE, which will make it pretty choppy. It's not ideal, but if you're an experienced surfer, the amount of water moving on Thursday the 13th afternoon (8 ft, NE, combined energy 932) is hard to ignore. Be prepared for a bit of a messy, bumpy surface, though.
Honestly, if you're after clean, lined-up waves, this forecast doesn't have much to offer. For the first week and a half, don't bother. The later part of the second week has size, but it's fighting the wind. For a beach break like 38 Line, that longer period (over 15 seconds) isn't an issue here because we never see it, but the short-period stuff is going to be pretty dumpy and disorganised when it gets big. This setup, with that strong onshore wind and the big, short-period swell on Thursday the 13th, might actually look more interesting for a kite surfer than a paddle surfer.
Keep your eyes on the 17th morning for a clean, manageable session, or brave the chop on the 13th for raw power. It's a waiting game.
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.
