The Lowdown
Alright, Rusty here. Let’s have a look at what we’ve got coming up for 38 Line.
Right off the bat, I’ll be straight with you – the next week and a bit is pretty flat. There’s nothing doing until late on Saturday the 29th, and even then, it’s just small, weak energy at about 2 ft from the NE with a period of 5 seconds. Low energy (45) and ordinary conditions. It’s a long wait.
We’ve got a real dry spell from now all the way through the end of August and into the first few days of September. Some mornings are glassy, but with next to no swell, it’s a paddling-around kind of deal, not a surf. The water temp is sitting at 80° which is much warmer than normal for this time of year, so at least you won’t be cold while you wait.
The first proper sign of life shows up on the 3rd of September, Thursday, with the swell picking up to 4 ft from the NE, but the period is a short 6 seconds and the wind is a cross-onshore. It’s not great, energy is 120 – still moderate. Conditions stay poor.
The real standout, and the only one worth circling on the calendar, lands on Monday the 7th of September. We’re looking at a solid 8 ft swell from the ENE with an 8-second period, clean and cross-off with a light breeze. The combined energy is up at 1008 – strong wave energy – and it’s flagged as excellent for experienced surfers. That swell size is over 8 ft, so it’s only for the crew who know what they’re doing. The crowds here are never an issue, so you’ll have plenty of room on that exposed E-facing bank. The wind is clean all morning.
Tuesday the 8th is still holding well, with 8 ft from the ENE, period at 8 seconds, and clean cross-off wind in the afternoon. That’s another solid day for the experienced crew.
Now, Wednesday the 9th sees a big 12 ft groundswell from the NE with a very long 10-second period, and the wind goes glassy. The energy is massive at 2577. But I gotta call it – it’s just too big for this break. That’s for the thrill-seekers with big boards and bigger balls, but for most of us, it’s a look-and-learn day. Take the Monday and Tuesday as your windows.
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.
