The Lowdown

Alright, crew, let’s cut to the chase. This stretch of coast is looking properly flat-out dead for the next couple of weeks. I’ve seen a lot of quiet spells, but this one’s a doozy. Don't get your hopes up for any decent paddle; the ocean is just taking a long nap.

The first thing that even resembles surf shows up on Thursday the 10th at 38 Line. It’s weak – about 5ft out of the ENE with a short, crumbly 7-second period. The energy is a paltry 207, so there’s no push to it. Add a light cross-onshore breeze, and you’ve got a bumpy, sloppy mess. You might get a couple of closeouts, but it’s hardly worth the wetsuit. Friday the 11th is dead flat, 2ft and glassy – calm as a pond, but that's it. No swell to speak of.

Then we hit a long, flat spell that runs well into the middle of next week. For days, the swell drops to under 2ft, and the energy readings are in the single or low double digits. Water temp is 76°, which is a bit warmer than usual for this time of year, so it’ll be pleasant for a swim, but that’s all. The wind is light or offshore, but with a flat ocean, it doesn’t matter. This is a solid five or six-day gap where there’s absolutely nothing on offer.

There’s a tease on the afternoon of Monday the 14th – a 5ft NE swell but with a brutal 20 km/h onshore wind. That blows it to bits. It’s just messy, choppy water, not surf. Not worth your time. By Tuesday the 15th, the wind calms down and it's glassy again, but the swell is only 2ft from the NE – a weak pulse. It’s clean, but there’s barely enough water moving to get your fins wet.

Now, the one to look at is Thursday the 24th. That’s over two weeks away, so take it with a grain of salt, but it’s the only real swell in the whole forecast. We’re looking at a 5ft ENE swell with a 6-second period, and the energy jumps to 257. The wind is light, so it might have some shape to it. It’s still a short-period swell, so it'll be a bit walled and sectiony on a beach break, but it’s something. It’s the only window where you might actually catch a decent wave.

So, there you go. A whole lot of nothing, with one faint maybe at the end of the month. The water’s warm, but the surf’s not. Be patient, check the buoy data later, and maybe dust off the longboard for the small stuff. Until then, I’m just watching the horizon.

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.
