The Lowdown
Alright, folks, Rusty here. Let’s take a look at what’s happening at Banzai. I’ve got to be honest, this is a tough one. The whole 16-day window is a bit of a dog. There’s no real stand-out session, and honestly, no surf worth paddling out for if you’re after anything decent. The finder is giving me nothing but "poor surf conditions" across the board, so we’re in a bit of a dry spell.
The first hint of any swell comes in on Friday, August 7th, with a weak 3ft SE swell, but it’s short-period at 6 seconds and the wind is a messy onshore ESE breeze. Combined energy is a paltry 64. That’s not going to do anything but chop it up. The water temp is sitting at 84°, which is about normal for this time of year.
We roll into the weekend and the pattern doesn’t really change. Saturday and Sunday, August 8th and 9th, see a bit more height, around 4ft to 4ft, but it’s all short-period, choppy, cross-onshore junk. The energy is weak, bouncing between 105 and 121. It’s a frustrating start.
The week of August 10th to 14th is more of the same. Monday the 10th has a 5ft swell but the wind is still cross-onshore, and the energy is moderate at 371. By Thursday the 13th, we get a 4ft ESE swell with a bit more energy (257), but the wind is still onshore. It’s always just a little bit off.
Now, Saturday, August 15th, is the one that’ll get your attention, but not for the right reasons. The data shows an 8ft ESE swell with a 12-second period and a massive 1880 energy reading. That’s a lot of water moving. But the wind is a strong cross-onshore E breeze at 15 mph. That’s going to be a washing machine, and at that size, it’s strictly for experts only. The break is a reef, so it could handle the size, but the wind is going to ruin it. It’s more likely to be a kite-surfing show than a clean paddle session.
The following week, from August 17th to the 22nd, the swell backs off. We’re back to 3ft to 4ft swells from the SE, with onshore wind. The energy values are mostly in the weak to moderate range. Tuesday the 18th is a write-off with a 4ft 6-second swell and only 78 energy. It’s a flat, frustrating end to the outlook.
So, to sum it up: there’s no treasure here. Banzai is an exposed reef, and it needs a clean window. This 16-day run is a total write-off for surf. The only real standout is the August 15th swell, but it’s a mess. Forecasts can change, but right now, I’d keep the board in the car and wait for a better day.
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.
