The Lowdown
G’day, it’s Rusty here. I’ve had a good look at the next 16 days for 38 Line, and honestly, it’s a tough start. We’re staring down the barrel of a long, flat spell with almost nothing to get excited about until the very end of the month. The water temp is sitting at 76°F right now, which is much warmer than usual for this time of year – a bit of a tropical feel.
From Saturday 18 July right through to Thursday 30 July, the surf is basically non-existent. Day after day of tiny, weak dribble – most of it under 2ft, with periods as short as 2 to 6 seconds and combined wave energy barely registering (often single digits). You’ll see a few glassy mornings, like Sunday 19 July with a 2ft east-northeast swell and no wind, but the energy is only 24, and the period is 5 seconds – it’s just not enough to push anything rideable. This is a real dry spell, and it’s normal for this area when the swell window goes quiet.
Then, finally, things start to change on Friday 31 July. The morning shows a 2ft swell from the southeast with a 10-second period, but the cross-onshore wind from the north-northeast at 9 mph chops it up – still poor. The afternoon, though, lifts to a 5ft north swell with a 6-second period and combined energy hitting 260 – still moderate but messy with onshore winds.
The real standout arrives on Saturday 1 August. The morning brings a 8ft northeast groundswell with a 10-second period, and the combined energy is a solid 1175. The wind is cross-off from the north-northwest at 19 mph, keeping it clean. This is big, powerful stuff – 8ft is expert territory, not for the faint-hearted. By the afternoon, it’s even bigger: 10ft from the northeast with an 11-second period and energy rocketing to 2664. The wind stays cross-off at 19 mph, and the conditions are clean, but the swell is predicted to be too big for this break. This is a serious, heavy day – only for the most experienced crew.
Sunday 2 August backs off nicely. The morning has a 5ft northeast swell, 10-second period, combined energy of 411, and the wind is light cross-off from the southwest at 6 mph – clean and good. The afternoon drops to 4ft from the northeast, 9-second period, energy of 208, and the wind goes offshore from the west at 12 mph, moderate breeze but clean. This is the best on offer for the whole run: solid, manageable groundswell with offshore winds.
So, to sum it up: don’t even bother paddling out until the end of July. The one true standout is Sunday 2 August – a day of fun, clean waves for intermediate to advanced surfers. Saturday 1 August is for the experts only, if you’re brave enough. Keep an eye on the long-range call – it’s promising, but still a week and a half away.
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.
