The Lowdown

Alright folks, Rusty here. Let’s cut through the noise and get straight to it. The next couple of weeks are a mixed bag, that’s for sure. We’ve got a bit of a flat spell coming up, so don’t rush to the water just yet. Patience is going to be key. But there’s a light at the end of the tunnel, and when it comes, it’s got some serious potential.

Right off the bat, the surf is pretty ordinary. Between now and the 14th of September, there’s just nothing doing. We’ve got a few waves in the 1ft to 4ft range, but the energy is weak, and the winds are just messy enough to keep things lumpy. The best you can say is Thursday the 10th is glassy with a 4ft wave, but it’s only packing a weak 178 combined energy and an 8-second period. It’s surfable, but you won’t be telling your mates about it. This is a real dry spell, and it stretches on for nearly a week and a half. Honestly, it's the kind of run that can make you forget what a decent wave feels like, but don't let it get you down.

Then things start to get interesting on Sunday the 20th. The swell starts to build, but the wind is a bit on it in the afternoon. The real standout, though, is Monday the 21st of September. There’s a proper pulse of north swell, showing 6ft in the morning with a 9-second period, and the energy jumps right up to a strong 1397. The wind is dead calm and it’s glassy. This turns 38 Line (Thirty-eight-line) into a proper proposition. It’s an exposed spot and this north swell is right in its wheelhouse, pushing it to be the standout of the entire stretch. The morning will be the pick, with clean, powerful lines. This one is for the experienced crew, though – at 6ft it’s getting serious, and it’s pushing past what you’d want for a learner.

The good news keeps rolling on the 22nd of September. Tuesday morning looks incredible for experts, with an 8ft east-northeast swell and an 11-second period, and the energy is very strong at 1752. Groundswell energy like that on an east-facing break means proper, pushing waves. But heads up – with a period that long, beach breaks can get a bit straight. This is where a defined break like 38 Line can be a real advantage. It’ll be one for the high-performance boards and those who know their way around a big, grinding wall. After that, we get a bit of a letdown. The wind swings around to the northeast and picks up hard on the 23rd, and with rain in the forecast, the quality is just going to be poor. It’s a classic case of the swell dropping right as the wind turns onshore. The energy is still there, but the conditions won’t allow us to enjoy it properly.

So, that’s the picture. A long, flat run-up. A fantastic Monday and Tuesday with real power and, for the most part, clean conditions. Cap it off with one final burst of size but messy winds to end the run. Don’t waste your energy on the early junk, and save your best for the 21st and 22nd. Mark it in your calendar and keep your fingers crossed the models hold together. It's a long way off, so treat it as promising but not a guarantee.

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.
