The Lowdown

G’day, Rusty here. Let’s break down what’s brewing at 38 Line.

Truth is, the next week and a half is a tough slog. From now until around the 4th of September, there’s a big empty stretch – mostly tiny, weak swell and messy wind or onshore junk. The water is sitting at 80°, which is way warmer than normal for this time of year – feels like a warm bath.

The first real chance of a surf comes on Saturday, 5th September, but it’s only a borderline call. We’ve got a solid 8ft swell from the ENE (combined energy 1386) – that’s strong energy. That’s expert-level – way too big for beginners. The morning wind is clean from the WNW, blowing cross-offshore, so the wave faces will be tidy. For an exposed east-facing spot like 38 Line, that ENE swell will hit hard. But the period is only 8 seconds – short-period wind swell, so it’ll be a bit lumpy and less organised. Still, for experienced surfers, that Saturday morning is the standout of the whole window. By the afternoon, it drops to 7ft, still clean, but the energy backs off.

Sunday, 6th September sees the swell fade fast to 4ft, with variable wind – not worth the drive.

After that, there are a few more flickers. Monday, 7th September has clean offshore wind from the W and WSW, but the swell is only 3ft to 4ft from the ESE. Small, but rideable and clean for a small-wave board. Tuesday the 8th turns glassy in the morning with a tiny 3ft easterly swell – good for a longboard or a foiler, but nothing serious.

The rest of the second week is light and patchy. There’s a bit more energy on Wednesday 9th afternoon, with 7ft from the NE, but it’s cross-shore wind and lumpy – skip it. Thursday 10th and Friday 11th have clean conditions again, but the swell is small, between 3ft and 5ft.

So, the one and only standout is Saturday morning, 5th September – big, powerful waves for experts only, with clean offshore wind. Nothing else in the 16-day window comes close. For the rest, it’s a waiting game.

Stay patient, watch the forecast, and don’t paddle out on the big day without your wits about you.

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.
