The Lowdown
Hey, Rusty here. Gotta be honest – the next two weeks at 38 Line are mostly a bust for surf. Plenty of flat, weak days before a couple of bright spots show up. Water temp’s about 75°F – a touch warmer than normal for now.
Monday afternoon the 14th is a write-off. A tiny 2ft NE swell, period barely 5 seconds, and a cross-on breeze from the NNE at 9 mph. Choppy and weak (energy at 26).
Tuesday morning the 15th is the first flicker of hope: 3ft from the NE, 6-second period, but the wind goes dead calm – glassy. Combined energy is moderate at 62. Surfable but nothing special.
From Tuesday afternoon all the way through Sunday the 21st, it’s tiny surf (1ft to 4ft), short periods (5–7 seconds), and mostly onshore or sideshore wind. Energy stays under 113. Honestly, not worth the paddle.
Tuesday morning the 22nd offers a cleaner window: 4ft E swell, 7-second period, with a clean cross-off breeze from the NNW at 6 mph. Energy is 111. Still ordinary, but the wind helps.
The real standout – the one to mark on your calendar – is Wednesday morning the 23rd of September. Swell hits 5ft from the ENE, 8-second period, and the wind goes glassy from the NW at 3 mph. Combined energy is 286 (moderate). That’s the cleanest wave of the whole outlook. Beginners might find the size a bit much, but for intermediates, it’ll be fun.
Thursday the 24th morning stays glassy but the swell drops to 4ft.
The second week fades. Friday afternoon the 25th brings a big pulse: 7ft from the NE, 8-second period, energy soaring to 533 (strong). But the wind is cross-on from the SSE at 6 mph, making it rough and only for experienced surfers. The rest of the week fizzles into tiny, weak leftovers (as small as 0.7ft) with poor conditions.
Best call: Wednesday the 23rd morning. That’s the one to chase. Otherwise, leave the board at home.
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.
