The Lowdown
G'day, Rusty here, and I've gotta be straight with you—this stretch ahead for Banzai is a real rough patch. We're looking at a solid 16-day window, but the surf is flat out not cooperating. Every single day, from Tuesday the 25th of August right through to Wednesday the 9th of September, is marked as "poor surf conditions." The wind is mostly onshore or cross-onshore, with gusts from the ESE and SE, which keeps the surface messy and chopped up. The swell is tiny, with heights barely scraping 3 ft or 4 ft, and when it does push up a bit—like toward the end of the first week—the energy is still weak to moderate at best, reaching only 301 (moderate) on the Sunday morning of the 30th. But with that onshore wind, it's just not going to be surfable.
The water temperature is sitting right around 85°, which is about average for this time of year with a 1° anomaly—nothing unusual there. The swell periods are short, mostly 6 to 8 seconds, and coming from the SE or ESE, which isn't the optimum direction for this reef break—it prefers a south swell. The combined energy is weak, with most values under 100, and even the highest later on—like the 346 on Sunday the 6th of September—is still just moderate. For a break that's fairly consistent, this is a tough run, but it does happen. The conditions are so poor that the setup looks more interesting for kite surfing than paddle surfing, if you're into that.
There's no standout session here—nothing to recommend. The first week is a total write-off, and the second week from the 1st of September onward doesn't get any better, with the swell dropping even lower. Hang tight, check the forecasts again, and with a bit of luck, things might shift. But for now, leave the boards at home.
Rusty.

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