The Lowdown
Alright folks, Rusty here. Let’s break down the next couple of weeks for 38 Line.
To be honest, it’s looking like a pretty flat and quiet period. The first time you might want to even think about paddling out is Tuesday the 15th. There’s a tiny 2ft swell from the NE with a short period of 6 seconds and a combined energy of 86. The only good thing going for it is the wind: glassy and offshore from the WNW at 3 mph. The surface will be clean, but the waves are small and weak. It’s surfable, but nothing to write home about.
Wednesday the 16th and Thursday the 17th are basically a write-off. The swell drops off and the wind turns onshore, so you’re looking at flat and bumpy conditions.
Friday the 18th sees a slight bump to 3ft to 4ft of easterly swell, with the energy climbing into the moderate range (111). But the wind is a cross-onshore from the NE at 9 mph, so it’ll be choppy and messy. Not great.
The weekend isn’t offering much. Saturday the 19th morning has a clean cross-off breeze from the NNW at 6 mph on that 3ft ENE swell, but it’s still small. Sunday the 20th morning is glassy, but only 3ft. It’s all very average.
Then we hit another flat spell. Monday the 21st through Thursday the 24th has nothing but onshore or choppy conditions on tiny swell.
The one session that has my attention is way out there, on the morning of Tuesday the 29th of September. We’ve got a glassy morning with a 4ft ESE swell, a period of 7 seconds, and the energy hits 125. With the wind turning glassy from the NNW at 3 mph, the surface should be clean. It’s a beach break, and the period is short, so don’t expect any long walls, but it’s the best-looking window in the whole forecast. Of course, that’s a long way off, so it’s promising, but not a sure thing.
So, to sum it up: the next two weeks at 38 Line are mostly small, weak, and wind-affected. There’s no standout day that screams “go surf.” If you’re itching for a session, the cleanest windows are Tuesday morning the 15th and the morning of Tuesday the 29th, but keep your expectations in check.
Stay tuned, things can always change.

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.
