The Lowdown
Alright, Rusty here. Let's have a look at what’s cooking for 38 Line over the next couple of weeks.
Alright, first off, it's a pretty slow start. The first few days are a bit of a write-off. We've got small, weak, short-period windswell, and even though the wind is light or glassy, the waves just don't have any push. The combined energy is barely registering, like 59 (moderate energy) on Tuesday morning, then it just drops off. It’s not worth paddling out for those waist-high, gutless lumps.
The first real chance of something half-decent rolls in around the 20th of September, that Sunday morning. We see a slight bump in the swell to about 3ft from the ENE, with a 7-second period. The combined energy hits 99 (moderate energy). The wind is a light cross-offshore from the NNW, which should keep things reasonably clean. It's not a standout, but it's surfable, and for this stretch, that's a win. The crowd factor is unknown, so you might have it to yourself.
Things get a bit more interesting on the 22nd of September, Tuesday. We've got another ENE swell, this time a little bigger at 4ft to 4ft, and the period is still short at 7 seconds. The combined energy jumps to 119 and then 174 (moderate energy). The wind is glassy on the Tuesday morning, and then a light cross-offshore in the afternoon. This is the best of a fairly average run. The waves will be soft, but clean. It's the pick of the period if you're desperate for a paddle.
Now, there is a pulse of energy around the 23rd of September, but it's a complete mess. We see a 6ft swell from the NNE with an 8-second period, but it's accompanied by 20-35 km/h cross-shore winds and rain. The combined energy is 648 (strong energy), but the quality is garbage. It's going to be a lumpy, choppy, rain-splattered shambles. Honestly, that kind of setup looks more interesting for kite surfing than paddle surfing.
The true standout of the whole 16-day window is the 24th of September, Thursday morning. We've got a solid 5ft swell from the ENE, with a period stretching out to 9 seconds. The combined energy is a respectable 355 (moderate to strong energy). The wind is glassy from the SSE, which means it's going to be clean. The crowd situation is unknown, but for this break, with this quality, it could get a little busy. This is your best bet by a long shot. Expect clean, head-high waves with some proper push.
After that, we're back to small, weak, and often onshore conditions. The end of the month sees a few pulses of 5ft to 6ft swell, but the wind is always cross-onshore, making it choppy and uninviting. The energy is there, but the quality is not.
So, to sum it up: the first week is a slow grind. The 22nd offers a clean, small option, but the 24th of September is the one to circle. A clean, fun morning with decent swell. Everything else is either too small, too messy, or too far away to get excited about.
Rusty out.

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.
