The Lowdown
Alright, Rusty here. Let’s take a look at what’s cookin’ for Crash Boat over the next couple weeks.
Honestly, for the first week and a half, it’s pretty grim. We’ve got a long stretch of tiny or flat conditions, with barely a ripple. From the 13th right through to the morning of the 24th, it’s all small stuff—most of it under 2ft—and it’s almost all cross-off or very light offshore wind. The combined energy is pitiful, mostly single digits or low double digits, which is just weak. There’s a few glassy moments on the morning of the 17th and again on the 20th, but with no swell to speak of, that’s just a flat, pretty ocean. Not a single standout in that whole block.
Now, the real news comes on Thursday the 24th. We finally see a pulse of north swell showing up. Thursday morning brings in a 3ft wave from the north, with a period of 10 seconds and a combined energy of 212 (moderate wave energy). That’s the first time we’ve had any real grunt. The wind is glassy in the morning, and then turns offshore from the NE in the afternoon. That’s a good sign. The water temp is sitting around 85°F, which is about average for this time of year.
But here’s the catch—Crash Boat is a sheltered spot, and it’s rated as inconsistent. For an advanced crew, that 3ft north swell with a 10-second period and offshore wind could offer a few clean lines, especially if you’re patient. The combined energy bumps up to 244 in the afternoon (still moderate). It’s not a monster, but it’s the best we’ve got by a mile.
After that, we drop back into tiny stuff again for the rest of the month. The 27th and 28th show a little more north-northwest pulse—2ft to 3ft—with moderate energy in the 66-132 range, but the wind is cross-off or light offshore, so it’s clean but small. Nothing that’ll get your heart racing.
So, if you’re really jonesin’ for a paddle, the standout window is the 24th of September. That’s your best bet. The rest of the outlook is a long, flat wait.
Stay patient, and keep an eye on the charts. - 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.
