The Lowdown
Alright, this is Rusty checking in. We've got a long look ahead for 38 Line, and I gotta be straight with you—it's a tough stretch. The finder is basically telling me there's no proper surf on the table for the next two weeks.
Right now, starting Thursday the 16th, we've got nothing. Tiny 1ft windswell from the SE with a short, weak 5-second period and almost no energy (4). The water's cooked at 78°, which is a massive 6° above normal for this time of year – that's very unusual, feels like bath water.
That flat spell runs all the way through the weekend. We get a little bump Saturday the 18th with a 5ft to 5ft NNE swell, but it's sloppy. The energy picks up a bit (133-209), but it's crossed up by wind and rain. The waves are there, but they're not rideable. Sunday the 19th offers some glassy conditions in the morning with 4ft NE swell (157 energy), and the calm wind makes it look clean. But the notes say it's still just ordinary – surfable but nothing to write home about. That's the closest we get to a window, but I can't recommend it.
After that, from Monday the 20th right through to Thursday the 31st, it's just a long, long run of tiny waves. Most days we're looking at 0.3ft to 2ft, with periods under 8 seconds and combined energy rarely breaking 60. A couple of mornings have glassy conditions, and the 28th and 30th have some clean offshore winds, but there's simply no swell to work with. Even the little pulse on the 29th with 3ft SE swell is messy with cross-onshore wind.
Honestly, for this whole 16-day stretch, there's no standout. It’s a total bust for paddling. If you're desperate for a session, the cleanest windows are Sunday morning the 19th or maybe Tuesday the 28th, but you'll be scratching for scraps.
This is Rusty, signing off.

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.
