The Lowdown
Alright, let’s get into it. The surf outlook for the next 16 days is a bit of a mixed bag, with a lot of flat spells and poor conditions. The first real opportunity isn't until the weekend of the 9th, but even then it's not great. We’ve got a long gap of nothing good before that.
Things start off real quiet. Thursday the 6th and Friday the 7th are basically flat, with tiny 0.7ft to 1ft swells and glassy morning winds, but there’s just no energy to work with. Saturday the 8th morning sees a tiny bump to 2ft, but it’s cross-onshore and messy. The afternoon picks up a bit with a 6ft swell from the NNE, but the wind is a cross-offshore, so it’s clean but the quality is still poor. Sunday the 9th is similar, with a 6ft NE swell and clean cross-off winds, but the overall energy is moderate (316). It’s still not great surf, just slightly better than the rest.
Then we hit a real dry spell. From Monday the 10th all the way through Tuesday the 18th, the surf is mostly small, weak, and onshore or cross-onshore. There’s a brief moment on Thursday the 13th with a 6ft ENE swell and a period of 9 seconds, giving a decent energy reading of 407, but it’s cross-onshore and choppy. Not worth the paddle. The only real standout in this whole period is Friday the 14th morning. 38 Line wakes up with a clean 4ft ENE swell, 8-second period, and a light cross-offshore wind from the NNW. The energy is moderate (201) and the conditions are clean. It’s not a massive swell, but it’s the best on offer for the whole outlook. The water temperature is a very unusual 82°, which is much warmer than normal for this time of year.
After that, it drops off again. Saturday the 15th morning is surfable but ordinary, with 3ft and clean conditions, but the energy is low (100). From the 16th right through to the 21st, it’s back to tiny, weak swells and poor conditions. The 21st is the last day in the window, with a pathetic 2ft SE swell and cross-onshore wind.
So, if you’re keen, the best bet is Friday the 14th morning at 38 Line. It’s the only window where the wind and swell line up for a clean session. The rest of the time is a struggle. Even then, it’s nothing to get too excited about.

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.
