The Lowdown

Alright, this is Rusty, and I’m looking straight at the charts for 38 Line. Let me break it down for you.

Honestly, mate, the next couple of weeks are looking pretty flat and quiet for this spot. We’ve got a long stretch of nothing special on the horizon. The first solid recommendation doesn’t pop up until Thursday the 27th of August, and even then, it’s more of a “we’re desperate” kind of session than a proper standout.

From now until the 27th, it’s all small, weak, and messy. We’re talking ankle to knee-high dribble with tiny periods, mostly around 4 to 6 seconds. The combined energy is really low, often just single digits, and the wind is all over the place – cross-off, glassy, onshore... none of it matters when there’s basically no swell. The water temp is a toasty 77°, which is about normal for the time of year.

Finally, on the morning of Thursday the 27th, we get a tiny pulse. We’re looking at 2ft of swell from the NE, with a period of 6 seconds. The combined energy is a weak 42, and while the wind is glassy, the waves are just “surfable but very ordinary.” It’s a small, weak day for a paddle.

The next glimmer of hope comes on Saturday the 29th of August in the morning. Same story, really: 2ft from the NE, period of 8 seconds, combined energy of 48. Glassy wind again, but it’s still just “surfable but very ordinary.” You’ll get a few little knee-high rollers, but you won’t be writing home about it.

The biggest energy spike in the whole 16-day window hits on the afternoon of Monday the 31st of August. The combined energy jumps to 193, which is a moderate pulse, but the swell is only 3ft from the SSE with a period of 7 seconds. The problem is the wind is a gentle cross-onshore, making it choppy. It’s not the clean, lined-up wave you’re hoping for.

There’s nothing here that I’d call a true standout. The best bet is probably the morning of Saturday the 29th of August for a glassy but small session. The period is a bit longer at 8 seconds, which is better than the rest, but don’t expect much. This is a long, drawn-out flat spell, and it’s one of those times where the forecasts can change, so keep an eye on it, but don’t hold your breath.

Stay patient, groms.

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.
