The Lowdown
Gap at the start here, folks. The first week and a half of this 16-day stretch is pretty much a flat spell. We're looking at nothing but tiny, short-period leftovers with combined energy readings barely cracking double digits—weak stuff, 3 to 21, nothing with any push. The swell direction is mostly from the south, which is not what Crash Boat wants. It's sheltered from that direction, so the small bits that do show are just not getting in. The wind is offshore and clean for most of it, which is a tease. It's clear, the water's warm, but there's just nothing to ride.
Looking at the whole run, the one that stands out as the *best* is the 19th of August, Wednesday morning. That's the first time we see the swell swing around to the north, with a 1ft swell at 8 seconds, and the energy jumps to 21—still weak, but a step up. It's light offshore wind from the NE, clean conditions, but it's inconsistent, and this is a spot that rarely gets good. You'll be scratching for them. After that, it's back to the small stuff.
The second week is more of the same, tiny south swells, mostly clean winds, but nothing with any power. There is a rogue 2ft SSE swell on the 25th of August with a 4-second period, which is just bumpy junk, not worth your time. A couple of afternoons with risk of thunderstorms, but that's about it. If you're a beginner, none of this is too big; in fact, most of it isn't big enough. The water's running about 85°F at the start, which is pretty much average for this time of year.
Honestly, this is a period where you're better off fixing your board or going for a paddle. There's nothing here that gets the heart rate up. It's a blank run, and for this area, that's not unusual.

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.
