The Lowdown
Alright, Rusty here again. Let’s cut to the chase—this Banzai forecast is rough for a while. There is no decent surf on offer for the first week, maybe even longer. We’re looking at a stretch of small, weak, onshore slop from the 27th through the end of August and into the first few days of September. The combined swell energy is mostly under 120, and the wind is blowing onshore or cross-onshore nearly every session. Not worth getting wet.
The first hint of something real is on Saturday the 6th of September. That morning, the swell reaches 5ft from the southeast, with energy climbing to 211. It’s still light onshore and marginal, but at least there’s a pulse. The next morning, Sunday the 7th, is similar—5ft SE swell, energy of 248—but again, it’s onshore and not clean.
The one standout in this whole 16-day run is Tuesday the 8th of September in the morning. Swell hits 6ft from the southeast, and the combined energy jumps to 592—that’s strong, real energy for this spot. The wind is cross-onshore, so it won’t be perfect, but there’s enough power that Banzai (Big Island) might actually start showing some shape. That’s the session to aim for, but it’s still not a classic. The period is only 8 seconds, so it’s not a long-period groundswell—more of a windswell, so expect it to be a bit walled and not as clean. Water temp is about average for this time of year, nothing weird.
After that peak, it fades quickly. The afternoon of the 8th drops off, and by the 9th and 10th, we’re back to weak 4ft dribble with onshore winds. Honestly, with this forecast, the only day I’d even consider is the morning of the 8th, and even then, it’s a gamble. If you’re really keen, maybe the Sunday morning before, but it’s marginal. From now until that Tuesday pulse, there’s over a week of nothing.
Banzai is a reef that can handle some size, but with constant onshore flow and short period, it’s not going to be the clean, hollow reef we all want. For most days, this setup looks more interesting for the kitesurfers than for us paddle guys. We’ll have to wait it out, but forecasts can change. You know how it goes.
Rusty out.

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.
