The Lowdown
Alright, gang, Rusty here again, but this time in feet and knots. So, 38 Line – the outlook is the same story, just different numbers. The first week is a total bummer. From Monday, 24 August, through the end of the month, it’s flat. Tiny waves, knee-high at best (0.3 to 0.6ft), and the swell energy is weak (2 to 12). Some glassy mornings on the 26th and 28th look nice, but there’s nothing to ride.
The first real pulse hits Saturday afternoon, 29 August. We get a bump to around 4ft from the ESE, a 6-second period, and the wind goes glassy. The combined energy jumps to 209 (moderate), and the models say “expect good surf conditions.” That’s the highlight for the near-term. It’s small but clean. Sunday the 30th has some 3–3ft leftovers, but the quality drops.
The morning of Monday 31 August looks glassy again with a 4ft NE swell (energy 144), but it’s ordinary. After that, the wind turns ugly with a lot of cross-onshore chop. The best bet for the whole forecast lands on Tuesday morning, 08 September. That’s over a week away, so keep your fingers crossed, but it’s a solid call. We’re looking at 4ft from the NE, clean cross-off wind from the NNW, and a combined energy of 244 (moderate). The waves won’t be massive, but they’ll be clean and rideable, which is the best we’ve got.
Water temp is about normal for this time of year, nothing wild.
That’s all from me, 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.
