The Lowdown
G’day, Rusty here. Let’s break down what’s happening on the 38 Line.
Right off the bat, we’ve got a long stretch of nothing. From Wednesday the 29th of July right through to the morning of Thursday the 6th of August, it’s flat. Tiny waves, poor conditions, not a thing to get excited about. The water’s a balmy 78°F which is much warmer than normal for this time of year, but that’s the only highlight.
The first real sign of life shows up on the afternoon of Friday the 7th of August. The swell jumps to 13 ft from the ESE with a period of 9 seconds. That’s a solid groundswell, and the combined energy is a massive 2398, which is strong. But here’s the catch – the wind is light cross-shore, which is clean, but the height is well over 8 ft. This is only for experts. The break is pretty exposed to the east, and the optimum swell is from the east, so the direction is right. But it’s too big for most. If you’re a seasoned charger, this is the standout.
Saturday the 8th of August morning makes it even bigger. We’re talking 16 ft from the SE with a period of 11 seconds. That’s a long-period groundswell, and the combined energy reads 6557 – very strong. Again, light cross-shore wind, so it’s clean. But 16 ft is massive. This is for absolute experts only. The swell direction is a bit off from the optimum east, but the size and energy are undeniable. The afternoon drops to 10 ft from the SSE, still big, but the wind turns cross-onshore, which is a bit lumpy. Still, for the big-wave crew, this is the best on offer.
After that, it drops away quickly. Sunday the 9th of August is back to small, weak surf, and the rest of the run into the second week is poor. Monday the 10th and Tuesday the 11th are small and messy with rain showers, and by Wednesday the 12th of August, the swell tries to build again but the wind is fresh and onshore, so it’s choppy and ugly. On Thursday the 13th of August, the swell is 6 ft from the NE with a period of 9 seconds, and the wind is cross-offshore, so it’s clean. The combined energy is 567, which is moderate. The morning session looks okay, but it’s a week and a half away, so treat it as a promising but less certain prospect.
In short, the first week is a write-off. The only real action is the big, dangerous swell on the 7th and 8th of August. It’s a serious, expert-only window. The water is warmer than usual, but that doesn’t help with the size.
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.
