The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for 38 Line is a tough one. We’re looking at a long stretch of small, weak, and often messy surf. The water is sitting at 81° with a 3° anomaly, which is much warmer than normal for this time of year, so at least you won’t need a thick wetsuit.
The first real chance to get wet comes on Tuesday morning, August 11th. It’s only 3ft of swell from the ENE with a short 7-second period, so the energy is low (82). But the wind is glassy, making for a clean surface. It’s surfable, but very ordinary – you’ll be fighting for scraps.
Wednesday the 12th sees a bump in size to 5ft from the ENE, period stretching to 8 seconds, and the energy jumps to moderate (287). Not too big for intermediates, but the wind is a messy cross-shore from the north. Expect a cross-chop on the face. Thursday the 13th is a write-off with rain showers and onshore wind. The swell jumps to 6ft from the NNE, and the energy is strong (805), but the conditions are choppy and poor. This setup looks more interesting for kite surfing than paddle surfing.
Friday the 14th offers a brief reprieve. The swell drops back to 4ft from the NE, but the morning brings a clean, cross-offshore wind from the NW. It’s still only a 7-second period, and the energy is low (181), but it’s the cleanest wave of the week. You’ll get a few rideable ones, but nothing to write home about.
After that, it’s a grim run. From Saturday the 15th all the way through to Tuesday the 25th of August, the swell is tiny – often below 2ft – with very low energy, rarely breaking 100. There are a few glassy mornings, but the waves just aren’t there. You’ll be staring at a flat, glassy ocean. This is a long gap of over a week with no real surf on offer.
The only other faint glimmer is on Monday morning, August 17th. A 4ft swell from the SE with a 5-second period, glassy wind, but the energy is still weak (90). It’s surfable but very ordinary again.
The standout? Honestly, there isn’t one. The best on offer is Tuesday morning, August 11th, for the glassy conditions, or Friday morning, August 14th, for the cleanest wind. But neither of them are true standouts. It’s a waiting game.
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.
