Table - best surf conditions forecast for 38 Line over the next 16 days.
Right then, let’s have a look at what’s on offer around here. Honestly, it’s a pretty flat run for the next couple of weeks. We’ve got 38 Line on the radar, but the first real sign of something rideable doesn’t show up until Wednesday the 15th, and even then it’s a bit of a tease.
The water temp is sitting at 73°, which is a touch warmer than normal for this time of year, so that’s a nice little bonus if you’re getting in.
Alright, let’s break it down. The first few days are a write-off. Tiny, weak, and messy. Monday the 13th and Tuesday the 14th are offering nothing but knee-high dribble with poor surf conditions. Not worth a look.
We get a little pulse on Wednesday morning the 15th from the southeast at 4 ft, with a period of 8 seconds. The combined energy is moderate (138), but the wind is cross-offshore from the WSW at 16 mph, which keeps it clean. The problem is the quality is still listed as poor, so it’s not a standout. By Wednesday afternoon, the swell drops to 2 ft and the wind goes offshore, but it’s very ordinary.
The real standout, if you can call it that, is Monday the 20th. We’ve got a morning glass-off with a northeast swell hitting 4 ft and a period of 7 seconds. The combined energy is moderate (111), and with glassy conditions from a light NNE breeze, it’ll be the cleanest we see all outlook. The swell direction is from the northeast, which is a solid match for 38 Line’s optimum from the east. Crowds are never an issue here, so that’s a bonus. It’s still only surfable waves with very ordinary conditions, but in this flat spell, it’s the best on offer.
Between the 15th and the 20th, there’s a gap of a few days with nothing worth paddling for. After the 20th, it drops right back down. We’re looking at waist-high or smaller for the rest of the outlook, with a few glassy mornings on the 22nd, 23rd, 24th, and 25th, but the swell is so weak—combined energy in the single digits or low teens—that it’s not going to push you down the line.
Overall, it’s a lean period. The only real window is the morning of Monday the 20th. If you’re keen, that’s your session. Otherwise, it’s a good time to wax the board and wait.

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.
