The Lowdown

Alright, Rusty here again, but in feet and miles. This 16-day window for 38 Line is a tough nut to crack. For the first two weeks, there’s just no good surf to speak of, and we’ve got a long, quiet gap until things finally start to show some life. The water is sitting at 27° which is much warmer than normal for this time of year, so if you’re just floating, it’s nice, but for surfing, it’s a waiting game.

The pattern starts off with a real dud. Sunday the 2nd through to the end of the first week gives us tiny, weak swell with poor conditions. The combined wave energy is basically nothing – we’re looking at values like 39, 75, even as low as 6. The swell is small, mostly 1 to 3 feet from the north or northeast, with periods around 6–7 seconds. That’s short-period, weak, windswell stuff. Winds are cross or cross-onshore, chopping it up. There’s a brief moment on Tuesday morning, the 4th, where the wind goes light and cross-off, making it clean, but the swell is only 3 feet from the northeast and the energy is a measly 52 – surfable but very ordinary. The rest of that week is glassy but tiny, or choppy and messy.

The second week kicks off with a bit more size but still poor quality. From Saturday the 8th afternoon, we see the swell start to bump up – 4 feet, then 6 feet from the northeast on Sunday the 9th, and energy climbs into the hundreds (137, 358, 450). But the wind is all wrong – cross-onshore, choppy, and accompanied by rain and thunderstorms. The surf is there, but it’s a mess. This pattern sticks around through the middle of the week, with the swell staying around 4 to 6 feet, but the wind never cleans up. It’s a kite surfer’s setup, not a paddle surfer’s dream.

Then, finally, we get a glimpse of hope. The real standout is Monday morning, August 17th. The swell is 7 feet from the northeast, with a period of 8 seconds, and the combined energy is a solid 507 – that’s strong, powerful stuff. The wind is light and cross-off from the NNW, which means clean, lined-up waves. This is the best on offer, and it’s a solid intermediate-to-expert wave given the size. Sunday morning the 16th is also worth a mention – 6 feet from the northeast, energy at 378, and light cross-off wind from the NNW making it clean. It’s a notch below the Monday, but still a good session. Just keep in mind, these are the only two real standouts, and they’re over a week away, so the forecast confidence is a bit lower – promising, but not locked in.

So, the call: grind through the long wait of flat, choppy, and rainy days. The reward is a clean, punchy northeast swell on the morning of Monday the 17th, with a solid backup on Sunday the 16th. Get out there when it’s clean.

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.
