The Lowdown
Alright folks, Rusty here. It’s a tough run of it for the coming weeks at 38 Line. Let's get into it.
The first real chance of waves comes on Friday, August 14th, but it’s a frustrating one. We’re looking at a 4ft swell from the northeast with a short, weak period of 7 seconds. The combined energy is moderate at 156, but the wind is a cross-off from the NW, which is not ideal for the east-facing setup. The water is a touch warmer than average at 79°. It’s surfable, but it’s very ordinary. It’s not the kind of day you’d drive for.
From Friday afternoon, the surf drops off a cliff. We go through a long, bleak stretch from Saturday, August 15th, all the way through to Saturday, August 29th. That’s almost two full weeks of tiny, weak, or non-existent swell. The combined energy readings are mostly below 50, often down to zero. You’ll see glassy mornings and some light winds, but with nothing to ride, it doesn’t matter. Even the small knee-high pulses that show up lack any punch.
The best we have on offer, and it’s the only real standout, is Saturday, August 29th in the morning. A 5ft northeast swell starts to push in with a period of 7 seconds, giving a combined energy of 211. The wind is glassy, calm out of the north. That’s clean. This is the one day in the entire 16-day window that looks worth a paddle. It’s still a short-period swell, so the shape won’t be world-class, but it’ll be a fun, clean size for intermediate surfers. It might be a touch big for beginners. By the afternoon, the wind swings onshore from the ENE and the swell jacks up to 6ft, but the quality drops and it becomes marginal.
So, for the next two weeks, you’re waiting. A long flat spell, then a brief window of hope on the 29th. It’s a tough call, but that morning glass-off is the one to circle.
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.
