The Lowdown
Alright, mate. Rusty here. Let’s be straight with you—this outlook for 38 Line is a tough one. We’re looking at a long, dry spell with hardly any real surf to get excited about. The first little pulse of energy doesn’t show up until the weekend of the 19th, and even then, it’s pretty ordinary. After that, there’s another big gap of almost nothing until the very end of the month.
To start, the water temp is sitting at 78° – that’s way warmer than usual for this time of year, a proper anomaly. You’ll be in boardshorts, no question.
The first real chance to paddle out comes on Sunday, July 19th. The morning is looking glassy with a light ENE breeze, and there’s a 3ft swell from the NE, with a period of 6 seconds. The energy is weak, only reading 80 (combined energy). It’s surfable, but very ordinary. That afternoon, it gets smaller and a bit onshore, so grab the morning if you’re desperate.
Monday, July 20th, is glassy again but the swell drops to 2ft. The energy is practically nothing (16). Not worth getting out of bed for.
Then we hit a dead zone. From Tuesday, July 21st, all the way through to Thursday, July 30th, there’s almost nothing. We’re talking ankle-biters at best, with combined energy stuck in single digits. The wind is mostly light or glassy, which is a tease, but there’s simply no wave to ride.
The one standout in this whole 16-day window lands on Friday, July 31st. The morning brings a clean, cross-off wind from the NNW at 9 mph, with a 4ft swell from the ESE at 8 seconds. The energy finally kicks up to 128 (combined energy), which is the only real pulse of the forecast. This is the best on offer, but it’s still not a classic. It’s a fair-weather, fun-sized wave for intermediates. The afternoon gets a bit cross-on and smaller, so the morning window is your only shot.
After that, it fades back to nothing for the first couple of days of August.
So, bottom line: if you’ve got a board and nothing else to do, Sunday the 19th might give you a slide, but the real target is the morning of July 31st. Otherwise, it’s a long, quiet stretch for 38 Line. Forecasts can change, so keep an eye on it, but as it stands, don’t hold your breath.
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.
