The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
Honestly, it’s a pretty bleak stretch ahead for 38 Line. We’ve got a long, dry spell with hardly anything worth paddling out for. The first few days show some pulse of energy, but it’s messy and poorly timed, so don’t get your hopes up.
The period kicks off on Wednesday, 12 August with a cloudy morning, a 5ft northeast swell running at a short 7 seconds, and moderate cross-shore wind from the north. The water’s about average for this time of year. The combined swell energy is moderate (243), but conditions are poor and the wind’s putting a chop on it. That afternoon gets a little bigger at 6ft, still short period (8 seconds), and a clean face but the wind is still not right. By Thursday the 13th, we’ve got moderate energy (863) and a 6ft northeast swell, but the forecast is marginal and the rain’s not helping. It fades quickly from there.
Friday morning the 14th sees a 4ft NE swell with a 7-second period, light offshore winds, and clean conditions – that’s the best you’ll get this week, but the energy is weak (207) and the swell’s small. Still, for a patient surfer on a longboard, it might be worth a look. After that, it drops off: Saturday and Sunday are tiny, with combined energy in the teens and single digits. Glassy conditions on Saturday afternoon and Sunday morning, but the swell is only 2ft and 1ft, so you’re basically floating.
There’s a long gap of nothing from Monday 17 August through to the end of the forecast. The odd glassy morning pops up, but with swell heights under 2ft and combined energy often below 10, there’s nothing to ride. The water stays calm, the wind flicks around, but it’s a desert for surf.
The standout, if you can call it that, is Friday morning 14 August. It’s the only session where the stars align a little: 4ft NE swell, light offshore winds, clean conditions. For a break that’s fairly consistent, it’s disappointing that this is the best we’ve got. But for a few waves on a small day, it’s your window.
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.
