The Lowdown
Alright, crew, Rusty here with the long-range look at 38 Line.
Honestly, we’re in for a dry spell. The water’s sitting at 78°F, which is way warmer than normal for this time of year, so at least the swim is nice.
The first week is a total bust. From Thursday the 3rd through Monday the 7th, we’ve got weak, short-period wind swell from 2ft to 5ft, but the wind is onshore or sideshore, making it choppy and ugly. The combined energy is low, mostly in the 42 to 213 range. Not worth your time.
There’s a tiny window on the morning of Tuesday the 8th. The wind goes glassy, light from the south at 3 mph, and the swell is a clean 3ft from the ENE at 7 seconds. The energy is weak at 68, and it’s described as “surfable but very ordinary.” It’s the best we’ve got, but it’s still a groveler.
After that, it’s back to tiny surf. Wednesday the 9th morning sees a bump to 8ft from the NE at 8 seconds, with energy hitting 706 (moderate), but the wind is a strong cross-shore at 16 mph, making it a choppy mess. That’s more for the kite crew than us.
From the 11th through the 15th, the swell is barely 2ft, with periods of 5 to 7 seconds and energy dropping to 10 (weak). The wind does go clean offshore or cross-offshore at times, but there’s just no wave to ride.
The only other flicker is on Wednesday the 16th morning. Swell hits 4ft from the NE at 6 seconds, with energy at 124 (moderate). The wind is a clean cross-offshore from the NW at 9 mph, giving us clean conditions. Again, “surfable but very ordinary.”
The long-range into the 18th looks flat and clean, but not worth a drive.
The bottom line: This is a rough 16 days. The best shot is the morning of Tuesday the 8th for the glassy conditions, or the morning of Wednesday the 16th for a little more size and clean wind. If you’re jonesing, bring a log and low expectations.
Stay patient, it’ll come back.

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.
