The Lowdown

Alright, Rusty here, lookin' at the charts for the next couple of weeks. There's a bit of a quiet start, but we've got a few windows opening up that are worth paddlin' out for.

The first real chance to get wet is Monday morning, the 31st of August. It's not gonna be a world-beater, but it's something. 38 Line is showing 2.6ft of weak, short-period swell from the ENE, with a combined energy of just 44 – that's barely a ripple. The water is *much* warmer than normal for this time of year, about 79.2°, which is a solid 4.9° above average. The wind is glassy, so it's clean, but it's more of a bump-and-grind session than anything special.

That afternoon, Monday the 31st, things get a proper look. The swell lifts to 4.3ft from the ENE, the energy jumps to a moderate 204, and it's still glassy. That's the best window of the whole run – a proper afternoon session with clean, punchy little waves. This is your standout. Crowds are never an issue at 38 Line, so you'll have it to yourself.

Tuesday morning, the 1st of September, is still fun with 3.9ft from the ENE and calm glassy conditions, but the energy drops back to 118. Tuesday afternoon, the wind shifts onshore, and it goes to junk. Wednesday and Thursday mornings are clean but small, with cross-offshore winds and waves around 3.3 to 3.6ft from the NE. Consistent, but nothing to call home about.

After that, it turns ugly. Friday the 4th through to the end of the first week is a write-off – onshore winds, choppy, and poor conditions. Saturday the 6th has a small glassy morning, but it's only 3.3ft and the energy is weak at 102.

The second week is a real mixed bag, mostly poor. A few glassy mornings pop up on the 8th, 9th, and 10th of September, with tiny waves around 3.0ft to 3.3ft from the ENE, but the energy is weak (60 to 99). The wind is often calm or light, so it's clean, but the swell is pathetic. From the 11th onwards, it's a total bust – strong winds, tiny swell, and a lot of chop. The 15th of September shows a late spike in energy to 225 with 3.9ft from the ENE, but it's hammered by a moderate cross-onshore wind, so it's messy and not worth it.

Honestly, if you're not in the water Monday afternoon the 31st, you're waiting a long time for next to nothing. It's a lean stretch.

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.
