The Lowdown
Alright, folks. Rusty here. Let’s break down the 16-day surf forecast for 38 Line.
The first couple of weeks are looking pretty dead. The water is running much warmer than normal for the time of year at 27°, but that’s about the only good news.
We’re staring down a long stretch of tiny, weak waves and poor conditions. Through the first week of August, we’ve got ankle-to-knee-high dribble – 0.3m to 0.7m of short-period swell from the NE, with combined energy barely topping 44 (very weak). The wind is all over the place, but mostly cross or onshore, keeping things choppy and messy. There are a couple of glassy mornings on the 5th, 6th, and 7th, but the swell is so small and weak (6 to 26 energy), it’s hardly worth a look.
The second week through the 15th of August gets even worse. The swell drops to 0.2m or 0.1m, and the combined energy sinks to single digits (2 to 14). The wind stays onshore or cross-onshore from the NE, and there’s rain showers. It’s a total blank run – nothing to recommend.
Then, just when you’re about to hang it up, there’s a real glimmer on the 16th of August. Sunday morning shows a jump to 1.9m from the NE, with a period of 8 seconds and combined energy hitting 403 (strong). The wind goes glassy offshore from the ESE. Sunday afternoon is even better: 2.1m from the NE, a period of 8 seconds, a massive 469 energy, and dead calm glassy conditions. The wave report says “expect good surf conditions.” This is the standout of the whole forecast. For a beach break, that 8-second period means the waves will have some shape and power. At over 1.5m, it’s not for the beginners, and at 2.1m, it’s strictly for the experts. But for those who can handle it, this is the session. The crowds at 38 Line are never a problem, so you’ll have the place to yourself.
So, to wrap it up: a long, flat, and frustrating 16 days, but the 16th of August saves it. The call is for Sunday the 16th – both morning and afternoon, with the afternoon being the absolute best of the lot. Get it while it’s good.
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.
