The Lowdown
Alright, Rusty here. Let's talk about what's on the menu for the next couple of weeks.
Honestly, mate, it’s a flat spell. We’re looking at a long stretch of barely a ripple, so don’t bother waxing up just yet. The first couple of weeks are a write-off for any proper surf. The water temp is a touch warmer than normal for this time of year, sitting at 77°F.
From Wednesday, July 22nd, right through to the end of July, the energy is almost non-existent. The combined swell energy is a measly 8 on the 22nd, and it barely gets into double digits. The swell is tiny, mostly around 0.7ft to 2ft, and with short periods around 4 to 6 seconds, it’s just wind slop. Winds are variable, but the swell just isn’t there to do anything with it. We get a few glassy or offshore moments, but they’re on a flat ocean. It’s a real bummer.
The first week of August isn’t much better. From Saturday, August 1st, through to Wednesday, August 6th, the combined energy finally starts to bump up a little, hitting 30 on the 4th, but the swell height is still only 2ft with a period of 7 seconds. That’s not enough to get excited about, and the winds are cross or cross-on, so it’s going to be messy and weak.
There is simply no standout session in this whole 16-day window. The break 38 Line is exposed, but with no swell to speak of, it’s just a lake. If you’re desperate for a paddle on a flat day, it’s fine, but don’t expect a wave. The forecast might change, but for now, it’s a long dry spell.
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.
