The Lowdown
G'day, Rusty here. Alright, mate, let's have a proper look at what's coming down the pipe for the next sixteen days. Honestly, it's a bit of a mixed bag, with a long dry spell before we see anything worth paddling out for.
To kick things off, the first decent chance we get is on the morning of Wednesday, the 2nd. 38 Line is looking at a clean 4ft of swell pushing in from the NE, with a period of 8 seconds. The water's sitting at a balmy 78°, which is a good 4° warmer than normal for this time of year. Combined swell energy is moderate at 125, but the real magic is the glassy offshores from the NNW. It's going to be dead smooth out there. It won't be huge, but for a Wednesday dawny, it'll be worth a look.
Now, after that little window, it turns pretty average. From Thursday the 3rd right through until Tuesday the 8th, the conditions are just grim. Onshore and cross-shore winds, lumpy, choppy, and messy. Not worth the effort. The combined energy readings are all over the place, some moderate, but the wind and swell direction just kills it.
The next real standout window comes in on the morning of Wednesday the 9th. This is the pick of the whole outlook. The morning is looking clean again, with a nice cross-off breeze from the NW at 6 mph. The swell jumps up to a clean 4ft from the NNE, and the combined energy is strong at 244. The period is a short 7 seconds, so it won't be as powerful as a groundswell, but with those light offshores, the faces will be smooth and lined up. This is your session.
The following days, from the 10th to the 16th of September, get messy again. The swell gets bigger, hitting 7ft and even 7ft, with combined energy readings climbing to 771 on the 16th. But the wind is a problem – it's mostly a moderate cross-shore chop from a northerly direction, which will make for a bumpy, challenging wave. For the majority of surfers, the bigger days won't be worth the hassle. The afternoons on the 15th and 16th might have some size, but the quality looks marginal. For now, stick with that glassy morning on the 9th.
Keep an eye on the forecasts, because it could change, but as it sits, Wednesday the 9th is the one.
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.
