The Lowdown
Alright, mate, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
First up, the bad news: there’s nothing worth paddling out for at 38 Line for the entire 16-day window. Every single session from Monday 20 July through to Tuesday 4 August is marked as poor surf conditions. The swell is tiny – mostly 0.3ft to 2ft – with periods under 8 seconds, meaning weak, short-period wind slop. Combined energy readings are all below 100 (weak), often just single digits. The water temperature is 77°F, which is 4°F warmer than usual – very noticeable for this time of year, but that warmth doesn’t help the waves.
Now, 38 Line is a fairly consistent spot, exposed to the east, with an optimum swell direction from the east. But we’re not seeing any decent E swell. Instead we get scraps from NE, ENE, SE, and even SSE – all tiny. Winds are occasionally glassy or light offshore (W on the 22nd morning and 26th morning), but with almost no wave height, it’s flat. The combined energy even dips to zero on a few days (25th, 26th afternoon, 2nd August afternoon). So it’s a blank run, plain and simple.
Because the break is usually fairly consistent, this kind of dead stretch isn’t typical, but it happens. Forecasts can change, so keep an eye on the charts – for now, save your energy and wax the board another day.
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.
