The Lowdown
Alright, let’s talk about Banzai. I’ve been staring at the charts for this stretch, and honestly, it’s a tough one to call. For a spot that usually has some fire in its belly, we’re looking at a long, flat spell with no real recommendations across the entire 16-day window. That’s a bummer.
Right from the start on Thursday, September 3rd, and all the way through to Friday, September 18th, the story doesn’t change much. We’re talking about tiny swell, mostly around 2ft to 3ft, sometimes pushing up to 5ft, but the quality is consistently poor. The wind is almost always onshore or cross-onshore from the ESE or SE, which kills any chance of a clean face. The swell period is short – 5 to 8 seconds – so there’s no power or push behind it. The combined wave energy is mostly weak (under 100), with only a few days showing moderate energy (like 117, 167, 264, or 498), but even then, the conditions are just too messy.
The water temperature is sitting around 85°F, which is about average for this time of year, so at least the bath water is nice.
There’s really no standout window here. Even when the swell bumps up a bit around September 9th and 13th, with heights touching 5ft to 5ft and a slightly better 8-second period, the wind is still onshore. That’s not going to give you the classic Banzai wall. For beginners, anything over 5ft starts to get intimidating, but here the wind and chop would make it even less fun. For experts, there’s just nothing to get excited about.
Honestly, this stretch looks more interesting for kite surfing than paddle surfing, given the consistent onshore wind and the lumpy, wind-affected surf. It’s one of those runs where the ocean just isn’t cooperating for Banzai. Forecasts can always change, but right now, I’d say leave the board at home.

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.
