The Lowdown
Alright, this is Rusty. Let’s have a look at the outlook for Crash Boat.
Honestly, mate, it’s a tough stretch. We’re looking at a long, quiet run with barely a ripple for days on end. The first recommendation doesn’t even pop up until Thursday the 24th of September, so that’s nearly two weeks of flat or near-flat conditions before we see anything worth paddling out for. Don’t hold your breath on the early stuff – it’s all tiny, weak, and messy.
The real story starts around Thursday the 24th of September. We finally see some life with a small northerly swell starting to push in. The water temp is sitting at about 86°, which is about 2° warmer than usual for this time of year – it’s a bit bath-like, but nothing too wild.
The standout window looks like Saturday the 26th of September. The morning has a clean 2ft northerly swell with a period around 10 seconds, and the combined energy is moderate at 82. The wind is a light cross-off from the ENE, keeping the surface tidy. It’s not huge, but after such a long flat spell, that’s the best we’ve got. The afternoon sees the wind pick up and swing more east, making it a bit bumpier, so get on it early.
For the few days before that, like Thursday the 24th and Friday the 25th, there are small 2ft northerly swells, but with shorter periods and lighter energy in the 50s and 60s. It’s clean enough, but weak. Not a standout by any stretch.
Because the swells are small and the period is moderate, this break will be more suitable for beginners and longboarders through this period. The northerly direction is what Crash Boat likes. The winds are mostly offshore or cross-off, so the surface will be clean, but the lack of size and power means it’s more of a fun, small-wave session than anything exciting.
Crowds are listed as “sometimes,” so with these small, clean conditions, expect a few locals out but nothing crazy.
So, the takeaway: a long flat start, then a small but clean northerly pulse from the 24th to the 26th of September. The 26th morning is the pick. It’s not a classic, but after the drought, it’ll feel like a win.
Rusty.

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.
