The Lowdown
Alright, this is a tough one to call. It’s Rusty, and I gotta be straight with you – for the next 16 days, starting now through the end of August, the surf at Crash Boat is going to be a real struggle. There’s no swell on the calendar worth a damn, so we’re looking at a long, flat spell.
The first week is basically a write-off. You’ll see tiny scraps of energy, nothing over 1 ft, with swell periods all over the shop. The wind is often offshore or cross-off, which would be a dream if there was any wave to clean up. The combined energy is a sad little story, with values like 2, 3, or 4 (weak energy) – nowhere near enough to push a surfboard. We’ve got a few days of glassy conditions, like on the morning of the 18th, but it’s just flat.
The second week doesn’t offer any relief. The swell heights stay stuck at 0.7 ft or 1 ft, with weak energy readings (2 to 6). The water temperature is sitting at 84°, which is 0.9° warmer than average for this time of year, so about normal for the season. Honestly, the only thing that's consistent here is the lack of waves.
The only standout, and I use that term loosely, might be the afternoon of the 19th of August. It’s got a tiny 1 ft swell from the north with a 7-second period, and we’ll see a moderate offshore wind from the ENE at 12 mph. The combined energy hits 15 (weak energy), which is the highest we’ll see. It’s still tiny, but if you’re desperate, you might find a knee-high ripple. Don’t expect much.
For this forecast, if you’re an advanced surfer, you’re out of luck. The size is too small, and the setups are too flat. This spot is a beach and reef, and with these conditions, it’s more of a paddling pool than a surf break.
Rusty, signing off.

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.
