The Lowdown
Alright folks, Rusty here. Let’s get straight into it, looking at the next 16 days for Banzai. I gotta be honest with you, this is a tough one to write. The whole period is a bit of a flat spell, and I mean that. The swell is coming from the SE, which is not the optimum direction for this reef at all – it really wants something from the South to get good. So, we’re dealing with onshore winds straight out of the SE for almost the entire run, keeping everything messy and blown out. The wave comment is consistently “poor surf conditions” – that tells you everything. There is no standout session, no hidden gem day. The best you can hope for is a slight bump in energy around September 8th, when the combined energy hits 246 (moderate), but with a short 7-second period and onshore wind, it’s a no-go.
The first real chance at anything surfable doesn’t get going until September 5th, and even then it’s tiny. The gap from the start of the period is immediate – there’s nothing on offer right now. The whole 16 days is a washout. The swell height never gets above 5 ft, and the period stays short, below 8 seconds for most of it, which means weak, wind-affected waves. The water temp is about 85°F, which is 2°F warmer than normal – so it’s pretty average for this time of year, no real anomaly there. But that doesn’t help the surf.
The only flicker of something different is around September 18th, when the wind briefly drops to a light breeze and the swell period ticks up to 7 seconds, but the energy is still moderate (148) and the wind is still onshore. It’s a consistent pattern of disappointment. The crowd situation is “sometimes” at Banzai, but honestly, with this forecast, you won’t have to worry about anyone else out there. This is a classic case of the reef not being activated. If you’re a paddle surfer, you can leave the board at home. The whole setup, with the short period and strong onshore wind, looks more interesting for kite surfing than paddle surfing. Sorry, folks, but that’s the reality of this forecast.
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.
