The Lowdown
G'day, Rusty here. Look, I've been staring at the charts for Banzai and I gotta be straight with you – this 16-day window is a tough one. We're looking at a long, flat spell with nothing to get excited about for the first week and a bit. The onshore winds are relentless, mostly from the southeast, and the swell is tiny and weak. It's a bit of a bummer, but it happens.
The outlook kicks off on Sunday, the 6th of September, with a tiny 2ft southeast swell, but the wind is straight on it at 12 mph, and the wave energy is pathetic at just 21. It's a write-off. This pattern holds through to Monday the 14th, with the swell barely nudging up to 4ft at best, but the wind is almost always onshore or cross-onshore, making for choppy, messy conditions. The water temp is sitting at 85°, which is about average for this time of year, so at least a dip won't be a shock.
We get a little pulse of energy on the 18th of September, a Friday, with a 5ft swell from the southeast and a period of 7 seconds. The combined energy jumps to 341, which is moderate, but the wind is still a cross-onshore, making it "gentle cross-onshore and fairly choppy." On top of that, the swell is short period, so it'll be weak and crumbly. It's not a day for a paddle.
The only real standout, if you can call it that, is Wednesday the 9th of September. The morning shows a 6ft swell from the east-southeast, the biggest in the whole run, with a combined energy of 513. That's moderate wave energy. But it's still onshore wind at 9 mph and the report says "marginal surf forecast or questionable tide conditions." It's a fleeting maybe, not a proper go day.
In short, Banzai is a reef break that's fairly consistent, but it's getting hammered by the wrong wind direction and a total lack of quality swell. The setup is more interesting for kite surfing than paddle surfing right now. For a real session, we need a shift in the wind and some proper groundswell from the south. Until then, I'd leave the board in the car. This is a blank run, plain and simple.
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.
Banzai is 2 km (1 miles) from the city of Boca Chica. If you plan a holiday in Caribbean Coast - Dominican Republic, look for hotels and other accommodation in Boca Chica. Boca Chica has rooms for a wide range of budgets as well as car hire and transport links.
