The Lowdown
Alright, Rusty here. Let’s take a look at what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s gonna be a bit of a waiting game. The forecast is pretty flat and ordinary for the first week or so, with only a few windows of so-so surf. The standout day, if you can call it that, is Wednesday the 12th. We’ve got a bit of push from a 5.2ft ENE swell, and while the morning has a messy cross-shore wind, the afternoon cleans right up with a nice cross-off breeze out of the NNW. The combined energy hits a moderate 294, so there’s some push behind it, but the period is a short 8 seconds, so don’t expect any long lines. It’s an intermediate spot, 38 Line, and it’s exposed to the east, so it’ll catch whatever’s coming. The water is a balmy 82.4° and a massive 6.5° warmer than usual for this time of year – that’s really unusual, so you won’t need a thick wetsuit, that’s for sure. This spot is fairly consistent and you’ll never have to fight a crowd here, which is a bonus for such a small setup.
After that Wednesday afternoon window, it goes quiet again. Thursday the 13th gets a bigger swell, 6.9ft to 7.9ft, but it’s paired with rain and strong cross/on-shore winds that’ll chop it all to pieces – not worth your time. Friday the 14th morning offers a small clean-up with 3.6ft waves and a cross-off wind, but it’s ordinary.
Then we hit a real dry spell. From Saturday the 15th all the way through to Friday the 21st of August, it’s mostly flat or tiny dribble with hardly any energy – combined energy values barely crack 100, often sitting in the teens or single digits. A few glassy mornings pop up, like Sunday the 16th and Wednesday the 19th, but the swell is only 1.3ft to 3ft. You could probably have a fun float on a longboard, but there’s nothing worth paddling out for.
Finally, on Saturday the 22nd, there’s a little flicker of hope. Morning brings a glassy 3.3ft E swell, combined energy of 75 – weak, but clean. It’s surfable but very ordinary. Sunday the 23rd sees a bump in size to 4.6ft, but the wind swings onshore and it gets choppy again.
Honestly, if you’re keen, the best bet is Wednesday the 12th afternoon for a clean, punchy little session. Everything else is a longboard flat spell or a blown-out mess. That’s the read for 38 Line.

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.
