The Lowdown

Alright, let’s get into it. The next couple of weeks are looking pretty bleak for a decent wave around here, I won't sugar-coat it. We've got a long stretch of nothing, then a flicker of life right at the end that might just be worth circling on the calendar.

Right now, it's flat, and it’s going to stay that way for a while. From the 15th through to the 23rd of August, there is just no energy in the water. We’re talking tiny, non-existent surf. You'd be better off finding a lake to practice your pop-up than coming out here. The water temp is 78°, which is about normal for this time of year, so at least you won't freeze while you're staring at flatness.

A little puff of life shows up on the morning of the 24th, but honestly, it's still junk. We might see a 2ft wave, but the energy is weak, just 19 units, and the wind is messy. That afternoon the swell bumps up to 3ft with 94 units of energy, but it's a cross-onshore chop. It’s more of a kite-surfing vibe than a paddling one if you ask me.

The 25th morning is surfable but barely, with a 3ft wave and clean conditions. Still, it's pretty weak. This isn't why we live here.

Then, we get another flat spell into the 26th. That afternoon, the wind picks up strong from the SSE at 12 mph, making things choppy and ugly.

Now, here’s where things get interesting. Hold on to your board. The morning of the 27th of August sees a fresh offshore wind from the WSW at 19 mph, cleaning up a 4ft NE swell. The energy is starting to build, hitting 105 units. It's not there yet, but you can feel it coming.

But the real standout is the afternoon of the 27th. The wind settles to a moderate offshore from the WNW at 16 mph, and we should have a clean 5ft NE swell. The energy jumps to a solid 290 units. This is the first real window of opportunity. 38 Line, this is for you. The swell direction is ENE, which is pretty much right in your wheelhouse. It's going to be a proper little groundswell with a 7-second period, so nothing too crazy, but it'll have some push. Get on it.

The morning of the 28th keeps that NE swell going at about 3ft, but the wind drops off and it loses a bit of its punch, scoring a 1/10 with the energy down to 169 units.

The next couple of days are where the real juice is, though it comes with a caveat. The morning of the 29th of August we’re looking at a 6ft ENE swell with a period of 8 seconds and a massive jump in energy to 433 units. And the wind? Dead glassy. This is a great looking morning, but that 6ft might be starting to push it for the groms. For the more experienced among you, this is going to be fun.

The morning of the 30th of August is the big one. We're talking a 7ft NE swell, 9-second period, and energy readings go through the roof at 764 units. The wind is light and glassy from the NNW. This is the standout of the whole run. It's going to have some serious power behind it. At over 7ft, this is expert territory for sure. It’s a shame it’s showing signs of rain, but that’s a small price to pay. This is the one you've been waiting for, but it's at the end of the forecast window, so treat it as a promising possibility, not a guarantee. Don't book the day off work just yet.

So, there you have it. A whole lot of nothing, then a couple of mornings that could be proper. Keep your eyes on the 27th and the 29th, but the 30th morning is the one that has me amped. See you out there.

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.
