Table - best surf conditions forecast for 38 Line over the next 16 days.
Alright folks, Rusty here. Gotta be straight with you – this next stretch ain't exactly gonna have you paddling for your life.
We're looking at a massive 16-day run of nothing but small, weak surf at 38 Line. The whole dang period is a write-off for decent waves. From this Friday afternoon (10 July) all the way through to Saturday the 25th, it's flat or close to it. The combined swell energy barely touches double digits, with most readings sitting below 20 (weak) until Wednesday the 15th, where it briefly bumps to a still-weak 154. Even that spike is no good.
The swell is tiny, rarely cracking 2ft out of the SE with a short period of 5 to 6 seconds – that's weak windswell, not proper groundswell. The water at the start is 74°, which is a touch warmer than normal for this time of year.
There are a few moments where conditions glass off, like Saturday morning (11 July) and Sunday afternoon (12 July), or Monday morning (13 July). But you could have the smoothest surface on Earth and it wouldn't matter when the best wave height is a pathetic 1ft. Even the bigger pulse on Wednesday the 15th hits 4ft with a clean cross-offshore breeze from the SW, but with that short period and poor surf quality flagged, it's a frustrating tease – more like a pond ripple than a proper wave.
This break is exposed to the east, and the swell is coming from the SE, so the direction is okay, but the size just isn't there. There's no point sugar-coating it; this is one of those stretches where you're better off tuning up your gear or finding something else to do. The outlook is pretty bleak for paddle surfing.

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.
