The Lowdown
Alright crew, Rusty here with a look at the upcoming swells at Banzai. Let’s be honest right off the bat, this stretch is looking pretty grim for a proper surf. The whole 16-day window is basically a write-off for decent waves. We’ve got a long, flat spell with no real recommendations, so grab a coffee or a cold one, because we’re not going anywhere fast.
Looking at the run from Monday the 17th of August, it’s all onshore junk. Monday morning sees a weak 4ft swell from the ESE, but with a 9 mph cross-on breeze from the east, it’s just messy and choppy. The combined energy is weak at 139. That afternoon is even worse with a direct onshorer. Tuesday through to the weekend is more of the same – tiny swell heights, short periods under 8 seconds, and onshore or cross-onshore winds. The water temp is about average for this time of year, but that doesn’t help the flatness.
The only flicker of hope, and it’s a very faint one, comes around Wednesday the 26th of August morning. We get a tiny 1ft swell from the SE, but crucially, the wind swings to a light cross-offshore from the NNE at 9 mph. It’ll be clean, but with combined energy of just 20, you’d be scratching for anything rideable. For the rest of the run, we see bumps up to 4ft, but the onshore winds and short periods (7 seconds) will keep it choppy and unappealing. This setup looks way more interesting for a kite surfer than a paddle surfer.
Honestly, there’s nothing to get excited about here. It’s a blank run, and for this area, that’s not unusual when the trade winds lock in. Forecasts can change, but for now, don’t bother paddling out.
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.
