The Lowdown

Right then, let’s have a look at what’s on offer for 38 Line.

Honestly, mate, it’s a bit of a quiet stretch ahead. We’ve got a small window of something rideable right at the start, but then it’s a long, flat spell that stretches for well over a week. The first real action kicks off on Thursday, 13th August, but even then it’s not exactly firing. The swell is coming from the NNE at 6ft, but with a short period of 8 seconds, the energy is moderate at best (603). The wind is a cross-off from the NNW at 16 mph, which keeps the surface clean, but the wave quality is marginal. It’s a bit of a messy, lumpy combo for the intermediate crew.

The best of the lot, and I mean the only real standout in this whole 16-day window, is Saturday morning, 15th August. The wind drops right out, going glassy from the NNE at just 3 mph, and we get a tiny 3ft swell from the NNE. The period is a very short 6 seconds, so it’s not packing much punch – combined energy is only 56 – but those glassy conditions will make it feel better than it is. For a beginner or someone on a foamie, this is your session. It’s surfable, just very ordinary. The water temp is about average for this time of year, nothing wild there.

After that Saturday morning, it’s a ghost town. Sunday the 16th is tiny, and by Monday the 17th morning we get a pulse of 5ft from the SSE with a 5-second period, but it’s glassy, so it’s clean but weak. That’s the last gasp of anything worthwhile. From Tuesday the 18th onwards, we’re looking at wave heights under 2ft, with energy levels dropping into single digits. A lot of glassy mornings, sure, but no swell to back it up. It’s flat, plain and simple. The 38 Line is exposed to the east, and the optimum swell direction is from the east, so the ground is right, but the ocean just isn’t delivering. This kind of blank run happens here – it’s a normal part of the season.

So, mark your calendar for Saturday morning, 15th August. It’s the only real chance to get wet with clean conditions. The rest of the forecast is a write-off for paddling.

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.
