The Lowdown

Alright, Rusty here. Let’s have a look at what 38 Line's got lined up for us. The water’s sitting at a touch warmer than normal for this time of year, about 76°, which is a nice little bonus for an early paddle.

Right now, and for the next several days, it’s a bit of a flat spell. We’re looking at tiny ankle-snatchers through Friday the 13th, nothing that’ll get you excited. There’s a little bump early on Sunday the 15th with some clean, waist-high lines around 3 ft from the NE, but the energy is weak (43). It’s surfable but nothing special.

We’ve got a long quiet run through the middle of next week. The swell tries to pick up a touch around Friday the 20th and Monday the 23rd, but it’s still ordinary, with the best being a glassy morning on the 20th with 2 ft NE swell (46) and a calm, clean morning on the 23rd with 3 ft NE (44). Not standouts, just something to wet the line.

Hold onto your board for Tuesday the 22nd. That’s where it gets real. We’ve got a massive 10 ft E swell rolling in with a long period of 10-11 seconds, and the energy is pumping hard at 2706. But—and it’s a big but—it’s too big for this break. The wind is cross and messy, and the wave energy is just too much. This is expert-only, and even then, it’s going to be a washing machine. If you’re a kite surfer, this setup is looking way more interesting than for a paddle.

After that, things settle back down into the small stuff again towards the end of the month. The standout, if you can call it that, is that Tuesday the 22nd, but only if you’re a strong swimmer or a kite surfer who likes it wild. For the regular surfer, the best bet is probably the glassy, clean morning on Sunday the 20th, with waist-high NE swell and zero wind. That’s the one.

Rusty out.

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.
