The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one. We’re looking at 38 Line, and the outlook for the next 16 days is a flat spell. There’s no real surf to get excited about.
The window opens on Friday July 31st with tiny, knee-high waves at best, and it just doesn't get any better. Through the first week and into the second, we’re stuck with weak, short-period windswell that never gets its act together. The combined energy of all swells directed here barely cracks double digits, topping out at a measly 99 on Saturday August 8th, but even that comes with rain showers and a moderate cross-onshore breeze that’ll chop it up. The water is running about 80°F, which is much warmer than normal for this time of year, a solid 5°F above average, so you’ll be warm while you’re sitting there waiting for a wave that never comes.
There’s a long, drawn-out gap of nothing from July 31st right through to August 13th. The only time the swell pushes past knee-high is on the morning of the 8th, with a 3ft ESE swell, but the period is a weak 7 seconds and the wind is on it. That setup looks more interesting for a kite surfer than a paddle surfer. For the rest of the run, it’s tiny, it’s weak, and the winds are mostly cross or cross-on. Sunday morning August 2nd offers a brief moment of glassy conditions with a 1ft NE swell, but it’s still too small to get excited about.
The long-range outlook into the second week, from August 10th to the 15th, is even worse. We’re talking ankle-snappers with strong onshore winds. There’s no standout here, no hidden gem. It’s a blank run, and for this area, that’s pretty normal. The forecasts can always change, but right now, I’d 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.
