The Lowdown
Alright, let’s get real about Crash Boat. It’s a spot that’s been given a solid reputation, and I know why—when it works, it’s a fun wave. But looking at this 16-day window, I gotta say, it is a tough stretch for anyone paddling out here.
The water is running about 85°, nearly a degree and a half warmer than usual for this time of year, so it feels more like a bath than the open ocean. That’s fine for comfort, but it doesn’t help the lack of action.
Right now, from Sunday the 30th of August all the way through to the end of the first week of September, it’s basically flat. No swell energy to speak of. A few days show tiny 0.7ft to 1ft pulses from the south, with periods between 4 and 6 seconds—that’s weak, short-period wind chop, not proper surf. It’s not even worth mentioning separately. The combined energy values are all under 10 (0 to 6), which is nothing. Glassy conditions or light offshore winds on some mornings are the only silver lining, but you can’t ride glass. This stretch runs from the 30th through to around the 7th of September—a real dead zone.
Around the 10th of September, Thursday afternoon, we finally see a tiny flicker: 1ft from the south with a period of 10 seconds, giving a combined energy of 17. That’s still weak, but the period is actually decent for this spot. With a gentle offshore breeze from the NE, it’ll look clean, but the size is barely knee-high. Not worth suiting up for.
Then, on Sunday the 13th of September, something changes. We get a small pulse from the NNW—1ft in the morning, climbing to 1ft on Monday the 14th, with periods around 8 to 9 seconds. The combined energy nudges up to 20. Now, Crash Boat is sheltered, and its optimum direction is west, so this NNW swell isn’t ideal, but sometimes a little wrap-around finds the break. Winds are offshore or cross-offshore and light to gentle through this period, so the surface will be clean. Still, it’s ankle to maybe knee-high at best. For an advanced break that’s inconsistent, this is a pretty quiet run.
If you’re a kitesurfer, there might be more to play with on the windier days—the moderate breezes from the east on the 2nd and 6th of September could get you going. For the rest of us, it’s a board-off fortnight.

Information about the Crash Boat Surf forecast
The above surf forecast table for Crash Boat provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Crash Boat can be found by selecting the local surf guide option on the grey menu. Our Crash Boat 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 (Crash Boat) 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 Crash Boat 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.
