The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at 38 Line.
First up, the water’s running about 79°, which is a solid 5° warmer than usual for this time of year. Feels like bathwater, proper tropical.
Honestly, the next week and a half is a bit of a bust. We’re looking at a long stretch of tiny, weak waves. From Thursday the 30th of July right through to the morning of Friday the 7th of August, it’s just flat to ankle-high junk. Swell energy is in the single digits (5 to 18) most days, with the occasional peek up to 62. It’s pretty lifeless out there. The winds are light, and there are a few glassy windows on the 4th, 5th, and 6th of August, but with wave heights barely nudging 1ft and a weak 5-second period, there’s nothing to ride. You’d be better off taking a swim.
Things start to look a little more interesting by the weekend of the 8th and 9th of August. Saturday morning the 8th sees the swell energy climb into the hundreds (118) for the first time, with a chest-high 4ft from the NE. The period is still short at 6 seconds, so it’ll be a bit lumpy, but there’s enough juice to push you around. Winds are light and cross-shore, so it won’t be a total washout.
If you’re picking the best of a quiet period, I’d point you to Sunday morning the 9th of August. We’ve got a glassy start with the wind swinging light off the NW, and the swell is a knee-to-waist high 3ft from the ENE. The combined energy sits at 48, so it’s modest, but that glassy surface will make it feel way better than the size suggests. It’s surfable, just don’t expect any barrels.
Looking further out, the 14th of August (Friday afternoon) shows a bit of a spike in energy – 196 – with a 4ft NE swell. That’s more than a week away, so keep your expectations in check, but it’s worth keeping an eye on.
The real standout? There isn’t a proper one this run. The 38 Line is a fairly consistent spot, so this flat spell feels a bit drawn out. The forecast can flip, but for now, pack a wetsuit for the swim, not the surf.
Stay salty.
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.
