The Lowdown
Alright, I’m Rusty, and here’s the straight talk for 38 Line.
We’ve got a rough start. From Tuesday afternoon, July 28th, all the way through the morning of Thursday, August 6th, it’s mostly flat or tiny – like 0.1ft to 0.7ft scraps with no power. Water temp is a warm 78°, which is over 2° warmer than average for this time of year, so that’s a nice bonus even if the waves aren’t there.
The first real sign of life comes on Friday, August 7th. We see a 3ft swell from the east-northeast, but it’s got a cross-shore wind blowing at 12 mph, and the period is only 6 seconds. The combined energy is weak (90). It’s small and choppy, not a day to write home about.
Now, the big event is Sunday, August 9th. The swell jumps to 12ft to 15ft from the east-southeast, with a 9-second period. The combined energy is huge (1754 to 3332) – that’s strong to very strong. But the wind is howling onshore at 34 mph with heavy rain and thunderstorms. This is not for paddle surfing; this is more of a kite surfer’s dream. The following Monday, August 10th, still has solid 6ft to 6ft waves, but the cross-onshore wind keeps it messy and chopped.
The best bet in the whole 16-day window is Tuesday, August 11th. You’ll find 4ft to 4ft swell from the southeast, with a light cross-offshore breeze at 6 mph from the southwest. That keeps the surface clean. The combined energy is moderate (281 to 203). The period is still short at 6 seconds, so it’s windswell, but it’s the most surfable conditions we get. The swell direction is close to the optimum east for 38 Line, so it’ll have some shape. Crowds are never a problem here, so you’ll have it fairly quiet. For beginners, this 4ft to 4ft is manageable.
After that, it fades back to tiny, weak swell by Wednesday, August 12th. So, if you’re picking a day, Tuesday, August 11th is your best shot. The long-range stuff is promising but not set in stone.
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.
