The Lowdown

Right now, 38 Line isn’t doing much of anything, and to be honest, the next couple weeks look pretty flat and underwhelming. There’s a real gap of nothing worth paddling out for until things start to show a little life around Friday the 18th, but even then, it’s a marginal call.

The first real chance of catching something clean comes up Sunday morning, September 20th. There’s a small 4ft east-northeast swell rolling in at 7 seconds, with light cross-off wind from the northwest. The water’s sitting at 74°, which is a touch warmer than normal for this time of year – nothing crazy, but you’ll notice it. It’s surfable, but pretty average. Nothing to get too worked up about.

Monday the 21st has a bit of leftover energy, around 3ft, glassy conditions with no wind. It’s clean but tiny. You’ll be fighting for a wave that barely stands up. Not great.

After that, we slide back into another flat stretch from Tuesday the 22nd right through to Sunday the 27th. There’s a brief window on the 23rd with some cross-off wind and clean conditions, but the swell’s only 2–2ft and the period drops to 4 seconds. That’s just wind chop – not real surf. The energy’s almost non-existent, with combined swell energy sitting in the low double digits (11–13) and even dropping to 2 at one point. You’re better off doing something else.

Monday the 28th is the standout of the whole run, but even that’s a stretch. There’s a 5ft north-northeast swell showing up in the afternoon, with a 7-second period and combined energy around 200 – the strongest we see in this whole forecast. But the wind’s cross-onshore out of the southeast, so it’s going to be choppy and messy. 5ft is pushing it for beginners, and with that wind, it’s not going to be pretty. If you’re experienced and keen, there might be something to find, but I wouldn’t call it clean.

Tuesday the 29th has a brief moment with offshore wind out of the west at 12 mph, and the swell is 3ft – clean but small. That’s about as good as it gets for the back half, but it’s still marginal.

From there, it just fades out again. Nothing over 2ft, periods dropping to 4 seconds, and winds swinging all over. There’s a glassy morning on October 1st, but the swell is only 2ft from the southeast with a 4-second period – that’s basically flat with a ripple.

Honestly, if you’re chasing decent waves at 38 Line over the next two weeks, you’re going to be disappointed. The standout, if you can even call it that, is Monday the 28th, but the onshore wind will spoil it. The 29th with clean offshore is your best bet for a few small, clean ones. Keep your expectations low.

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.
