The Lowdown
Alright, Rusty here. Let’s have a look at the 16-day picture for 38 Line.
Honestly, mate, it’s a grim stretch. The whole 16-day window is a write-off for any kind of decent surf. We’re looking at a long, flat, and frustrating run. The forecast starts with a bit of swell on Saturday the 18th, but it’s a total mess – heavy rain, messy cross-shore winds, and a short-period, weak northerly bump that’s just not worth paddling out for. The wave energy is weak (50), and the conditions are poor.
From there, it’s a slow bleed. Sunday the 19th afternoon offers a tiny glimpse of something, with 2.6ft of easterly swell and a glassy surface, but the energy is nearly non-existent (51) and the period is a pathetic 6 seconds. It’s surfable, but only just, and you’d be struggling for a ride.
After that, the taps turn off. From Monday the 20th right through to the end of the run on August 2nd, we’re looking at flat to microscopic waves. The swell heights drop to 2.0ft, then 1.0ft, then 0.3ft, and for days at a time, there’s simply nothing – zero energy. There are long gaps of completely flat, glassy conditions, especially through the middle of the week. Even when a tiny south-east pulse shows up around the 29th of July, the energy is still in the single digits (13). The wave energy for the entire period is weak, barely cracking double digits for most of it.
The best you could say is that the wind is often light or glassy, which is nice for a paddle, but there’s nothing to ride. The swell direction is all over the place – north, east, south-east – but it doesn’t matter because there’s no size or period behind it. This is a proper blank run for the area. There’s no standout, no highlight, just a whole lot of nothing. Keep the board in the bag and check back in a week – forecasts can change, but this one’s a tough pill to swallow.

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.
