The Lowdown
Alright, let’s get into it. I’m lookin’ at the charts for your area and, mate, it’s a bit of a slow burn. We’ve got a window of rideable surf kickin’ off on Wednesday the 12th of August, but don’t get too excited just yet – it’s a short-lived pulse.
First up, 38 Line will see some chest-high, 5ft ENE swell, but the period’s a short 8 seconds, so it’s gonna be a bit lumpy. The wind’s blowin’ cross-off from the NNW at 16 mph, which keeps things clean, but the water’s a touch warmer than normal at 79°. Combined energy’s moderate at 277, so there’s some push, but it’s marginal conditions. Crowds are never an issue here, which is a bonus.
Thursday the 13th bumps up a little – we’re lookin’ at 6ft from the NNE early, still with that short 8-second period and a moderate 16 mph cross-off. The energy jumps to a solid 627, so there’s some grunt, but again, the quality’s on the fence. It drops off to 6ft in the arvo.
Friday the 14th is fading fast. Morning sees 5ft dropping to 4ft in the afternoon, and by then the poor surf label kicks in. Wind stays cross-off but it’s over. From Saturday the 15th right the way through to the middle of the second week, it’s a long, dry spell. For nearly two weeks – from Saturday the 15th all the way up to Wednesday the 26th of August – we’re lookin’ at nothing but flat or tiny, weak waves. The energy readings are mostly in the single digits or low double digits, less than 100, so the ocean’s just takin’ a nap.
There’s a flicker on Thursday the 27th of August. In the afternoon, a fresh offshore breeze from the W at 22 mph kicks in with a 2ft N swell. The combined energy is only 38, so it’s weak, but the wind is clean and offshore. It’s not gonna be a standout, but if you’re desperate for a paddle after that long flat spell, it might be worth a look for a tiny, clean wave.
Honestly, the real takeaway here is a short, average-quality window on the 12th and 13th, then a massive, flat gap. For this stretch, 38 Line gets the nod, but only just.

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.
