The Lowdown
Alright, let’s break this down. I’m Rusty, and we’re looking at the 16-day stretch for 38 Line, a fairly consistent, intermediate beach break that’s wide open to the east.
Right now, it’s flat. From Thursday the 30th of July through Friday the 7th of August, there’s basically nothing worth paddling out for – a full 9-day gap of tiny waves and poor surf. The combined swell energy sits in the weak range (under 100) for almost all of that time, often just 2 to 10. Winds are light and often cross-off or glassy, which would be great if there were any waves. But there aren’t.
The first real sign of life shows up on Saturday the 8th of August. The morning brings a clean, cross-off breeze from the NNW, and the swell finally shows up – waves around 5ft from the ESE with a 7-second period. The combined energy reads 237, which is moderate, so you’ll feel some decent power. Water temp is about average for this time of year, nothing weird. That Saturday morning is your best bet – the standout. It’s head-high and clean, with light winds keeping the surface tidy. The ESE direction isn’t the absolute best for 38 Line (it prefers straight east), but 5ft and clean is still a solid session for an intermediate. Crowds are never an issue here, so you’ll have your pick.
After that morning, it falls off. Saturday afternoon turns a bit onshore, and Sunday the 9th is onshore all day with waves around 3–4ft and energy dropping. Monday and Tuesday the 10th and 11th bring a little rebound – 3–4ft from the NE and ENE, periods around 5–7 seconds – but the wind is messy, and conditions are only so-so. The energy stays low to low-moderate (52 to 91). It’s surfable, but nothing to write home about.
From Wednesday the 12th onward, it fades back into small stuff – 2ft and under, with some glassy mornings but no real power. By Friday the 14th, it’s down to 1ft from the SE.
So, the story is simple: a long wait, nearly a week and a half of flatness. The one day to circle is the morning of Saturday the 8th of August. That’s your window. After that, it’s back to the small stuff.
Keep it 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.
