The Lowdown
Alright folks, Rusty here. Let’s get into it for 38 Line.
Truth is, if you’re hanging out for a wave at 38 Line over the next couple of weeks, you’re going to be waiting a long time. The first week and a half is a total write-off. From Tuesday the 4th of August right through until the morning of Thursday the 13th of August, it’s all poor surf conditions with near-zero scores. The water is much warmer than normal at 27°, sitting over three degrees above average, which is weird for this time of year, but with no surf to speak of, it doesn’t matter much.
The surf finally gets its act together on the morning of Friday the 14th of August, but even then, it’s only marginal. You’re looking at a 8ft swell from the NE with a period of 10 seconds, and the combined energy is hefty at 1444. That’s a lot of push, but it’s still coming in with a cross-shore wind from the NNE at 15 mph, making it messy. This is not a beginner wave – at 8ft, it’s for experienced surfers only. The water temp is still way above average, but the wind is the main spoiler here.
The only real standout in this whole 16-day window is the morning of Saturday the 15th of August. We get a drop in swell size to 5ft from the NE, with a period of 7 seconds. The combined energy is a more manageable 246. But the real kicker is the wind: a light cross-offshore breeze from the NNW at 12 mph. That’s going to clean things up nicely. The direction is NE, and while 38 Line is exposed to the east, the NE swell should wrap in okay. This is the best session on offer – clean, solid, and just big enough for a good time. Crowds are never an issue here, so you should have plenty of room.
The following morning, Sunday the 16th of August, is also worth a mention. The swell drops to 3ft from the NE, still with a 7-second period, and the wind is a light cross-offshore from the NNW at 9 mph. The energy is only 93, so it’s weak, but it’s clean. It’s a small, fun option if you’re desperate.
After that, the surf fades right back out to nothing from Monday the 17th of August onwards. So, bottom line: don’t bother for the first ten days. The morning of the 15th is your best bet for some clean, 5ft NE swell with a light cross-offshore breeze. Get it while you can.
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.
