The Lowdown

Alright folks, Rusty here. Let’s take a good hard look at what’s coming down the pike for 38 Line. Gotta be straight with you – this stretch of the forecast is a tough one for us paddle surfers.

We’re kicking off Tuesday, July 21st, and there’s essentially nothing worth paddling out for. For the first week and a half, we’re staring at a whole lot of flat, weak dribble. The combined wave energy barely scratches double digits, living down in the 1 to 11 range for days on end. It’s a real bust. The wind is light and often glassy, but there’s just no swell to work with. You’ll see a few 0.7ft to 1ft pulses from the ENE and SE, but with periods between 4 and 7 seconds, it’s just wind chop. Not a single decent wave in the bunch.

We finally see a change around Monday, August 3rd. The swell picks up, but it’s a tricky one. The morning brings a 6ft swell from the SE with a period of 7 seconds, and the combined energy jumps to 446. That’s moderate energy, but the short period means it’s going to be a bit of a mess. On top of that, we’ve got a light cross-onshore wind from the NE. It’s surfable, but it’s not the clean, groomed stuff we dream of. This is a window for the experienced crew only, as that 6ft with a short period will be a handful. The 4ft in the afternoon is a little more manageable, but the wind and chop remain a factor.

The real bright spot, and the only true standout in this whole 16-day window, is the morning of Wednesday, August 5th. The swell drops to 3ft from the SE, but the period is a touch better at 6 seconds. The key here is the wind: a light cross-offshore breeze from the NNW. That’s clean. The combined energy is still only 64, so it’s not a powerhouse, but it’s the best we’re going to get. The slightly longer period and clean conditions should offer up some fun, rideable lines for the intermediate surfer. It’s a welcome break from the nothingness.

Outside of that one Wednesday morning, the rest of the run is either flat or too messy. Overall, a pretty quiet run for 38 Line. Keep the board waxed for that one morning window, but don’t hold your breath.

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.
