The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for 38 Line. Honestly, it's a bit of a waiting game this time. The next sixteen days are a mixed bag, with a big chunk of flat, poor-quality days, but there is a little window that might just be worth a paddle.
The first real sniff of anything happens on Tuesday the 8th. Early morning, we get a tiny window with the wind going glassy, which is a huge plus for clean conditions. The swell is a small 3 ft from the E, with a period of 7 seconds. The energy is weak (115). It's surfable, but very ordinary. It's the kind of session you go for if you're desperate, not because it's pumping. Tuesday afternoon the wind swings and the quality drops off again.
The next thing to look at is Wednesday the 9th, but this is a dangerous one. We've got a solid 10 ft of NE windswell, with a short period of 8 seconds. The wind is howling from the NE at 19 mph, putting a real chop on it, and not in a good direction. The energy reads a massive 1169, which is strong, but it's going to be lumpy, onshore mess. For anyone but the most expert crew, this is a skip. It might look better for a kite session than a proper paddle.
After that, it goes quiet again until a brief moment on Friday the 11th. The morning is glassy again, but the swell is a tiny 2 ft from the E. It’s clean, but with the combined energy only at 64, it’s barely there.
Then, a long gap with nothing of note until Monday the 14th. Monday morning sees the wind go glassy with a 3 ft E swell, period of 6 seconds. The energy is 124, so it’s there, but it’s not exactly lighting up the dial. It’s another “surfable but ordinary” kind of vibe.
Beyond that, there’s nothing worth getting excited about. The swell fades to almost nothing, with a few glassy mornings that won't offer a wave worth paddling for.
So, to wrap it up: the standout session is really just Tuesday the 8th morning for the clean, glassy conditions, but don't expect any size. The bigger pulse on the 9th is a write-off for most surfers. If you had to pick one, take the glassy Tuesday morning, but keep the expectations real low. For the rest, you're better off waiting for the next proper swell.
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.
