The Lowdown
G’day, Rusty here. Let’s cut straight to it. The next couple of weeks are looking pretty bleak for Banzai. We’ve got a long stretch of nothing but onshore junk and weak, short-period swell. There’s a bit of a bump around the 16th, but it’s messy and not worth getting excited about. Honestly, if you’re set on getting wet, you’d be better off finding other things to do until this pattern shifts.
The 16th of August is the only time the ocean even tries to show some life. Sunday afternoon sees a 7ft ESE swell with a 9-second period, and the energy jumps up to 1313 – that's the strongest we see all window, describing a moderate to strong pulse. But don’t be fooled. It’s cross-onshore and choppy, with a risk of thunderstorms. The morning of that same day is bigger at 7ft but even messier, with an 884 energy reading. This is a case where the size is there, but the quality is completely missing. The wind just kills it.
After that, it’s a slow, sad fade. From the 17th through the 30th, we’re looking at swell heights mostly under 4ft, periods of 5 to 8 seconds, and weak energy readings mostly below 200. That’s not surf, that’s just chop. The winds keep flipping between cross-on and onshore, and the water stays lumpy. There’s no point in even checking the cam.
So, to be straight with you: there are no good surf options in this 16-day window at Banzai. The one day with some size on the 16th is a write-off due to wind. The rest is flat or junky. For a reef break that needs clean lines, this is a total blank. It’s one of those stretches where you just leave the board in the car and watch from the cliff. The forecast can change, but right now, I wouldn't hold my breath. This is just one of those times the ocean takes a holiday.
Stay tuned, and hopefully, the next run has something for us.
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.
