The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks at 38 Line.
Right off the bat, I gotta be straight with you – the next week and a half is a real quiet stretch. The only real window to even think about paddling out is this Tuesday morning, the 8th of September. It’s not a standout, but it’s the only game in town for a while.
Tuesday morning, September 8th is the one to look at. The water is a touch warmer than normal for this time of year, sitting at 77°. We’ve got a small 3ft swell sneaking in from the ENE with a short period of 7 seconds. The combined energy is weak (114), so it’s not going to have much punch. The real beauty here is the wind. It’s dead calm, glassy conditions. That’ll make the surface as smooth as a lake. It’s surfable, but with that short period, it’ll be a bit soft and crumbly. It’s an intermediate wave on a good day, and with the lack of size, it’s a good one for a longboard or a mal.
After that morning, it fades fast. Tuesday afternoon gets a little bumpy, and then from Wednesday the 9th right through to the 16th, it’s a total write-off. We’re looking at a solid 8-day stretch of nothing worth mentioning. The swell disappears, the wind turns onshore or just stays messy, and the scores are all zeros. It’s a bad beat.
Now, if you’re patient, there’s a flicker of hope right at the very end of the forecast. On Thursday afternoon, September 17th, the wind goes glassy again and we’ve got a 4ft swell from the NE with a 7-second period. The combined energy bumps up to a moderate 218. The forecast says “expect good surf conditions” for that afternoon window. It’s still a week and a half away, so keep your fingers crossed, but it’s the best looking slot on the whole board.
Bottom line: The first week is a dud. Hit Tuesday morning if you’re desperate for a glassy, small-wave session. Otherwise, keep your eye on the 17th – that’s the one that could actually deliver.
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.
