The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the outlook for Banzai over the next couple of weeks is a tough one. We’re looking at a long stretch of poor surf conditions that’s going to leave the paddle-out feeling like a bit of a chore. Honestly, there isn't a single standout window in this whole forecast that I'd call a true winner.
The pattern starts now and it’s all a bit meh. For the first week, from Tuesday afternoon right through to the following Monday, the wind is mostly onshore or cross-onshore out of the SE to ESE at 9-16 mph. This keeps the surface messy. Swell heights are small to middling, between 3 ft and 6 ft, coming from the SE and ESE. The periods are short, sitting at 6-8 seconds, which means the waves are weak and lack any real push. The combined energy values are all over the place – some readings are in the moderate range, like 322 or 462, but the conditions just aren’t there to make anything of it. Every single session in that first week has a “poor surf conditions” tag. There’s a bit of a pulse on Thursday the 10th and Friday the 11th with that swell energy hitting 417 and 462, but the wind is just ruining it.
There is a gap of a few days with no improvement. From the 15th onward, it’s more of the same – persistent onshore and cross-onshore winds, small, short-period swell, and wave energy mostly in the weak to low-moderate range. The water temperature is running about average for the time of year, around 86°F.
Now, for the real kicker: this is Banzai, a world-class reef break that needs the right angle and size to fire. The optimum swell direction here is from the south, and while we do have some SE/ESE swell, the periods are too short and the wind is wrong. For a break that is "fairly consistent" but exposed and often crowded, a run like this is just a waiting game. It’s not a total shocker for the area – sometimes you just get these blank stretches where the forecast is as flat as it is frustrating.
If you’re desperate for a paddle, the best you’ll see is some 5 ft swell on the 9th, 10th, and 11th, but it’s onshore and short-period. Not worth the fight.
Stay patient, keep watching the charts, and hopefully the next update brings better news.

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.
