The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Banzai is a tough one to write. This is a reef break that needs specific conditions to line up, and for the next couple of weeks, the wind and swell just aren't playing ball.

We start with a quiet period. The first solid recommendation doesn't appear until much later, so from now through early September, the surf is a no-go. The swell is small, mostly under 3ft, and coming from the SE, which is directly onshore and messing up any chance of a clean face. The combined energy is weak, sitting between 27 and 158 (158 being the only moderate spike on Wednesday the 26th, but quickly ruined by onshore wind). The water temperature is sitting at 84°, which is about average for this time of year, so that’s not the issue.

The real problem is the wind. It’s relentless from the SE and ESE, blowing cross-on or directly onshore almost every day. This is a reef break that needs that NW offshore to make it special, and we just don't see it. The period is short, mostly 6 to 7 seconds, so no real groundswell energy to push through the chop.

Now, there’s a glimmer of hope in the second week. On Friday, September 7th, we see the swell size bump up to 4ft, still from the SE, but with a slightly longer period of 8 seconds. The combined energy jumps to 210, which is moderate. The wind is still onshore for the afternoon, but the morning of September 7th shows a light SSE breeze. That’s the only window that looks even remotely rideable, but it’s not a standout. The swell direction is SE, but Banzai’s optimum is S, so it’s not hitting the reef perfectly.

Then on Tuesday, September 8th, we get a jump in the afternoon. The swell is 5ft from the ESE with 8-second period, and the combined energy hits a massive 468. That’s strong to very strong energy. But the wind is still onshore from the SE. For a reef break like Banzai, that much energy with onshore wind is going to be a messy, closed-out, dangerous situation. I’d only recommend this for absolute experts, and even then, it’s a gamble. The crowds are noted as "sometimes," so when it’s on, the lineup can get busy, but with this forecast, it’ll likely be empty.

The rest of the run into the 8th of September is the same story: SE wind, onshore, small to moderate swell, poor conditions. It’s a stretch of flatness and blown-out slop. There’s no standout day here. The best you can hope for is a quick look at the 4ft on the morning of the 7th, but don’t hold your breath.

This is a spot that can be world-class, but it needs a proper S swell and that NW offshore wind. We just don’t get that in this 16-day window. Hard to get excited about this one.

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.
