Alright, I’ve looked over what we’ve got for the next couple of weeks, and I gotta be straight with you – it’s a tough stretch for 38 Line. The forecast is pretty bleak, with nothing but small, weak swell and mostly poor surf conditions from now all the way through to the 19th of July. We’re looking at a classic flat spell.
Right out of the gate, Saturday the 4th has a tiny 1ft SE swell with a short period of 4 seconds. The wind is a cross-on shore, making for choppy, messy conditions. The combined energy is only 7 – that’s just a whisper of energy. The water temp is sitting at 71°, which is about average for this time of year, so at least you won't be freezing while you sit there bobbing around.
Sunday the 5th morning starts with zero wind, completely glassy, but that 1ft swell is still anemic. You might see a couple of ripple-like waves, but it’s not surfable. This pattern of tiny, weak swell and mostly onshore or cross-shore winds just repeats day after day. We get a tiny bump to 3ft on the morning of Wednesday the 8th, with a combined energy of 43, and a light cross-shore wind which is a slight improvement, but at that size and with a short 4-second period, it’s just not going to have any push.
Basically, for the entire first week and into the second, there is not a single day that offers anything worth paddling out for. The swell heights barely tickle 2ft, the period is almost always under 6 seconds, and the energy values are all in the double digits or less. We're in a total lull.
The second week, from the 12th to the 19th, is more of the same. We finally see a little more consistent glassy or clean-offshore wind conditions, like the clear morning of Saturday the 11th with a clean cross-offshore breeze, and Sunday the 12th morning with a 6 mph offshore from the west. But the swell is still pitiful – 1ft with a 5-second period is just not enough to break properly. The combined energy stays at 13 or lower.
To be honest, this is a stretch where you’re better off putting the board away. The setup here, with these weak, short-period swells and onshore winds, would be more interesting for a kite surfer trying to get some marginal planing in, than for anyone trying to paddle into a wave. There are simply no standouts. It's a rare blank run where the weather looks nice but the ocean just doesn't cooperate.

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.
