The Lowdown
Alright folks, Rusty here. Let’s have a look at the outlook for 38 Line. It’s a bit of a tough stretch, so I’ll be straight with you.
Right off the bat, we’re looking at a pretty grim few days. The first real chance at anything surfable doesn’t pop up until Tuesday morning, the 8th of September. Before that, it’s all rain showers and choppy, messy cross-on winds. Not worth paddling out.
Tuesday morning, the 8th, is our only real glimmer of hope in the near term. The wind drops to nothing, and we get glassy conditions. The swell is tiny though, only 3 feet, coming out of the ENE with a short 7-second period. The combined energy is weak, only 79 (moderate wave energy). It’s surfable, but only just. It’s small and weak, so you’ll need a log or a funboard. The crowd factor is ‘never’ here, so you’ll have it all to yourself.
From there, things get ugly again. We get a spike in size on Wednesday the 9th, with the swell pushing 8 ft to 8 ft from the NE, and the combined energy jumping to 806 (strong to very strong wave energy). But the wind is onshore and choppy, ruining it completely. That’s a no-go for a paddle board; honestly, that setup looks more interesting for kite surfing than paddle surfing.
Then we drop off into a long, flat spell. From Thursday the 10th right through to the end of the 16-day window, we’re looking at tiny waves, mostly under 2 ft, with periods as low as 4 seconds. The wind does go glassy a few times, but there’s just no energy – the combined energy values are in the single digits or low teens. It’s a total flat spell for over a week. There’s a small bump in size on the 18th and 19th, but it’s still only 2 ft with a 4-second period, and the wind is messy. Nothing to report.
So, bottom line: the only window worth even considering is Tuesday morning, the 8th of September. Get out there in the glassy conditions for a tiny, weak knee-high wave. The rest of the period is a write-off. It’s a blank run, which is a bit of a bummer, but it happens. Forecasts can change, so keep an eye on it, but for now, the board stays in the car.
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.
