The Lowdown
G’day, Rusty here. Let’s be straight up: we’ve got a long, quiet stretch ahead at 38 Line. The first solid window is a good week away, so you’ll need patience.
The pattern starts with small, weak swell and ordinary conditions. Monday morning the 3rd of August offers a tiny 0.9 ft NNE swell with a short 7-second period and light cross-off wind, but it’s pretty average. The water is a very unusual 81°, which is 6° warmer than normal for this time of year – that’s a real standout. Combined wave energy is weak at 73.
From Monday afternoon all the way through to Sunday the 16th of August, it’s a long run of poor surf. Swell stays small, often under 3 ft, with periods under 8 seconds. Winds are mostly cross or onshore, and the energy is weak – most days sitting below 100. There’s nothing worth paddling out for.
The first real sign of life comes late in the outlook. On Monday morning the 17th of August, we get a glassy morning with a 4 ft ENE swell, period still short at 6 seconds, but the energy is moderate at 87. The comment says “surfable waves but very ordinary conditions” – it’s a start.
The standout is Tuesday the 18th of August. The morning brings a clean, glassy session with a 7 ft NE swell, 7-second period, and strong combined energy of 503. This is the pick of the whole forecast. The swell direction (NE) matches the optimum E swell direction reasonably well, so expect good shape. At 7 ft, it’s solid intermediate territory – beginners might find it a bit much. The afternoon turns messy with rain showers and a cross-on wind, so get on it early. That morning session is the one to circle.
Overall, a lot of flat, ordinary days, but that Tuesday morning the 18th of August is a true highlight. Keep your eyes on the forecasts, because it tends not to stay poor for long.
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.
