The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for 38 Line (Thirty-eight-line) over the next couple of weeks.
Right off the bat, it’s a bit of a slow start. The first few days are looking pretty flat and not worth paddling out for. There’s a long gap of nothing until we get to Saturday afternoon, the 29th of August, where a tiny bit of energy starts to show. It’s still only 4ft from the east with a weak period, so it’s really just a sign that things might turn.
The first real glimmer of hope comes on Sunday morning, the 30th of August. We’ve got a clean 3ft swell coming from the north-northeast, with an 8-second period, and the wind is glassy, light offshore from the north-northwest. The water is about average for this time of year, so no surprises there. The combined energy is moderate (210), and it’s the first time the forecast calls for *good* surf conditions. This is a solid window for a session, and the crowds are never an issue here, so you’ll have the place mostly to yourself.
After that, it drops back to small stuff again until things get wild. Don’t get too excited by the big numbers showing up in the first week of September. The 4th of September sees a massive 12ft to 15ft swell from the east and east-northeast, but the wind is howling at 25 mph from the north, creating a messy cross-chop. The combined energy is through the roof (1889 to 4268), but it’s a complete mess. That’s a kite surfer’s dream, not a paddle surfer’s. It’s only for the absolute experts, and even then, it’s going to be ugly.
The real standout, the one you want to circle on your calendar, is the morning of Wednesday, the 9th of September. We’ve got a solid 8ft swell from the north-east, with an 8-second period, and the wind is pure offshore from the west-northwest at a light 6 mph. The water will be clean as a whistle. The combined energy is strong (1237), and the forecast is calling for *excellent* conditions for experienced surfers. This is the best on offer – a proper, clean, decent-sized swell. It’s a bit far out to nail down completely, but it looks promising.
Thursday morning, the 10th of September, also has a nice, glassy 6ft north-east swell, so it’s a good follow-up session if you miss the Wednesday morning peak.

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.
