The Lowdown
Alright, Rusty here, let’s break it down.
Right off the bat, things are looking pretty grim at 38 Line. We’ve got a long dry spell ahead before anything worth paddling out for shows up. The first week is a write-off. From Tuesday the 8th to the 13th, it’s mostly small, messy, and wind-affected – not worth the wetsuit peel. On Wednesday the 9th, there’s a pulse of 8ft NE swell, but it’s getting hammered by a strong cross-onshore breeze, so it’s choppy and crumbly, definitely only for the experienced crew if you’re game, but honestly, it’s poor. The combined swell energy hits 974 (moderate energy) but with that wind, it’s a mess. Water temp is sitting at 76°F, which is about a touch warmer than normal for this time of year.
After that, the swell drops away fast. Friday the 11th and Saturday the 12th have tiny 1ft to 2ft waves with glassy conditions in the mornings, but it’s just too small to do much with – energy readings are down in the weak range (9 to 30). That pattern of tiny, weak surf carries on through the weekend and into the start of the next week.
Finally, we see something on Monday the 14th afternoon. A 4ft NE swell rolls in with a gentle cross-off breeze, giving clean conditions. Combined energy is 78 (weak). It’s surfable but very ordinary – not a standout, just the first sign of life.
Tuesday the 15th morning has a small 2ft NNE swell, glassy conditions with light rain, and combined energy of 42 (weak). It’s clean but tiny. That’s about it for the whole period.
After that, from the 16th right through to the 23rd, it’s a flat, weak run of small, low-energy surf, often with onshore or cross-shore wind. Wave heights barely hit 2ft, periods are short (4 to 7 seconds), and combined energy never gets above 20 (weak). The best you’ll get are a few clean mornings with glassy conditions on the 18th and the 22nd, but the swell just isn’t there.
So honestly, there’s no true standout session here. The whole 16-day window is a quiet stretch. If you’re desperate, Tuesday the 15th morning offers the cleanest conditions with a tiny bit of swell, but don’t expect much. This kind of blank run isn’t uncommon for the area, and forecasts can always shift, so don’t lose hope.
Stay patient,
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.
