The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for 38 Line.
Right off the bat, we’ve got a bit of a slow start. The first window of surf worth paddling out for is Saturday morning, August 29th. It’s not going to blow your mind, but we’ve got chest-high waves at about 3ft from the ESE, with a short period of 6 seconds. The wind is a cross-off from the NNW, so the lineup should be feeling clean. The energy is weak at just 68, so it’s more about getting a wetsuit on than scoring a barrel.
That afternoon the wind swings more northerly and gets a bit stronger, turning it into a cross-shore mess. The score drops and conditions go ordinary, so I’d be off the water by lunch.
Sunday morning, August 30th is where things get interesting. The swell jumps slightly to 4ft, coming from the NE, but the real magic is the glass. A NNE breeze at just 3 mph has the surface looking like a mirror. This will be your best session of the week. The combined energy is a moderate 135, and the break is picking up that NE swell. It’s fairly consistent, and with the crowds listed as never, you might have it to yourself. This is a standout for the whole outlook.
The following week is a real struggle. From Monday, August 31st through to the end of the first week, wave heights drop and the wind keeps turning onshore or cross-onshore. There’s a brief window on Monday morning, September 7th, where we get some 3ft glassy conditions from the ENE, but it’s low energy with only 104. Then a nice offshore on the Monday afternoon from the WSW at 12 mph, with a wave height of 3ft from the NNE and moderate energy (187). It’s surfable and clean, but still fairly weak.
Further out, around Thursday morning, September 10th, we get a tiny spike of 5ft from the north, but it’s coupled with a cross-on wind and the conditions look poor – fresh onshore and lumpy. The energy is moderate at 268, but the wind ruins it. This would be a messy paddle.
For the Saturday morning, September 12th, and into the next week, the swell drops back to nothing – 1ft or less. Not worth the wetsuit zipper.
The real standout of the entire outlook is that Sunday morning, August 30th. The 4ft NE swell with glassy conditions and low crowd potential at 38 Line is the best call. Get on it early.
Rusty, signing off.

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.
