The Lowdown
Alright, let’s put it in feet and degrees. The whole 16-day window for Banzai is a tough stretch – flat, windy, and ugly. There’s a big gap of poor conditions from the start, with no real surf worth paddlin’ for until the very end.
From Wednesday the 12th of August through Tuesday the 25th, it’s a desert. Onshore and cross-onshore winds blow every day, and the swell is tiny – mostly under 5 feet, with periods of 5 to 8 seconds, so it’s weak, choppy, and gutless. The combined wave energy starts at 33 (weak) and only gets up to 973 (moderate) on the 14th afternoon, but that’s still paired with onshore wind and poor quality. Water temp is 84°F, right around average for this time of year.
The only glimmer comes on the morning of Wednesday the 26th of August. Cross-shore wind from the east-northeast at 9 mph, and the swell hits about 5 feet from the east-southeast at 7 seconds. The combined energy is 318 (moderate), and it’s called “marginal surf forecast or questionable tide conditions.” It’s the closest thing to a session we get. The swell’s short period means it’ll be soft and lumpy, but it’s a break from the constant onshore mess. This is an advanced reef break, so beginners be warned. Crowds are “sometimes” a factor, so don’t expect solitude.
The 27th goes right back to onshore wind and small, weak swell. A real tough run, but Banzai is fairly consistent, so this flat spell is just a lull. Forecasts can turn. For now, there’s one day that’s barely worth a look.

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.
