The Lowdown
Alright folks, it’s Rusty here, and I’ve gotta be straight with you – the next couple of weeks at 38 Line are lookin' pretty grim for a proper paddle session. We’ve got a long, dry spell ahead before anything even thinks about shaping up.
Right now, from Thursday the 6th through to Sunday the 17th of August, it’s basically a write-off. The swell is tiny, the wind is all wrong, or the conditions are just plain messy. For the first few days, we’re talkin’ ankle-snappers of 0.6ft to 1ft with poor surf quality. The energy is in the single digits (7), so you’re not goin’ anywhere. Even when a bit of size shows up on Saturday the 8th with a 2ft swell, it’s cross-onshore and choppy. Not worth the wax.
Now, the end of the first week into the second week gets a bit of pulse, but the wind is a nightmare. From Sunday the 9th through to Thursday the 13th, we’ve got a buildin’ swell, but it’s all wall-to-wall with cross-onshore winds. The combined energy rises from 304 to a massive 2194, which is a lot of juice, but it’s blown out and messy. That 12ft swell on the 13th is a beast, but with a fresh cross-onshore wind, it’s just a washing machine. Only for the hardcore or the kite crew.
The only glimmer in this whole outlook comes right at the end. On Tuesday the 19th of August, we’ve got a bit of hope. The morning shows a 2ft swell from the NE with a 7-second period, and the wind is cross-offshore from the NNW. That’s clean. Combined energy is a weak 48, so don’t expect much push, but it’ll be rideable. Then on Thursday the 21st of August, things look a little better. We’ve got a 4ft ENE swell, still a 7-second period, but the wind is light and cross-off from the NNW. The combined energy is 160, and it’s glassy clean. That’s the pick of the whole 16 days – a proper small-wave session with clean faces. The break is exposed to the E, and this ENE swell is in the right zone. It’s not a standout by any means, but it’s the best on offer.
Overall, this is a frustrating run. For a break that’s fairly consistent, it’s a long stretch of bad luck. The swell is there, but the wind is a curse. Hang tight, the forecasts can change.

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.
