The Lowdown
G’day, Rusty here. Let’s be straight with you: this 16-day window for 38 Line is a pretty lean stretch. We’re looking at a long gap right from the start with nothing worth paddling out for, and then a few small windows that are just barely surfable. The best of a quiet bunch is coming up mid-month.
The first real sniff of a wave worth mentioning is on Tuesday the 8th of September in the morning. The water’s sitting at 77°, which is a touch warmer than normal for this time of year – nice for a shorty or just a spring suit. That morning, we get a glassy 3ft swell, coming from the ENE with a short period of 7 seconds. It’s not powerful, with combined wave energy at 114 (moderate), and the waves are surfable but very ordinary. Still, glassy conditions with no wind make for clean faces, and that’s about as good as it gets for a quiet patch. Crowds are never an issue here.
After that, we hit a big dry spell. From Wednesday the 9th morning right through to Monday the 14th afternoon, it’s pretty much all poor surf conditions. Wednesday morning does see a pulse of 8ft from the NE with a period of 9 seconds and energy reading 1046 (strong), but the wind is cross-shore and it’s showing marginal surf with questionable tide conditions. That’s a messy one, and honestly, for most surfers it’s a skip. The rest of that stretch is tiny, onshore junk.
We’re looking at a break of nearly a week with nothing recommended until Tuesday the 15th of September. That morning we get another glassy window with 3ft from the NE, 7-second period, and energy at 84 (weak). Surfable but very ordinary again. The afternoon holds a similar story with 3ft.
Wednesday the 16th brings heavy rain and strong cross-shore winds (19 mph) with a building 5ft easterly swell (energy 232, moderate), but the conditions are lumpy and messy. That setup looks more interesting for kite surfing than paddle surfing.
The final chance to get wet comes on Friday the 18th of September in the morning. Glassy conditions, 3ft from the east with an 8-second period and energy at 111 (moderate). Surfable but very ordinary. After that, the outlook fades into tiny glassy or light onshore waves right through to the 22nd.
If you’re set on a surf, the standout is that Tuesday the 8th morning. It’s small, clean, and about as good as this stretch gets. The rest is a waiting game. Forecasts can change, so don’t write it off completely, but right now, it’s mostly a blank run.
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.
