The Lowdown
Alright team, Rusty here. Let’s have a look at what Thirty-eight-line has in store for us over the next couple of weeks. It’s a bit of a slow burner, honestly. The first chunk of the forecast is pretty flat and not doing much of anything. We’re looking at a lot of mornings with tiny, weak surf and glassy conditions – real knee-slappers at best. The water temp is sitting at 75.4°, which is a touch warmer than usual for this time of year, so it’ll feel pretty nice even if the waves are lacking.
The first real sign of life doesn’t show up until the morning of Tuesday the 22nd. We finally see a pulse of energy with a 4.9ft east swell, and the wind is blowing lightly offshore. That’s the standout window, with the combined swell energy at 282 – a solid moderate push. It’s going to be clean and have a bit of shape to it. After that, the window closes quickly as the wind swings onshore and chops it up for the afternoon.
After that, it gets quiet again for a few more days. The run from the 23rd to the 27th is mostly poor, with small waves and messy winds. There is a blip on the morning of the 24th with a clean 2.6ft ENE swell, but it’s nothing to get too excited about. The final afternoon on the 27th sees a bigger 5.6ft NNE swell roll in, but the wind is cross-shore and onshore, so it’s likely to be a messy, blown-out sort of thing, and that’s the fault of the conditions not the swell. The energy is there at 212, but the quality won’t be.

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.
