The Lowdown
Alright, let’s be real with you. It’s a bit of a flat, mushy stretch ahead for the North Shore. I’m looking at Banzai, and honestly, there’s not a single day in this whole 16-day run that gets a green light.
The first week is just a write-off. We’ve got small, short-period wind swell from the southeast, mostly in the 2.5 ft to 4 ft range, and it’s arriving with onshore or cross-onshore winds. The energy readings are weak, mostly in the 40s to 170s, which just means there’s no push. It’s choppy, bumpy, and just not worth paddling out. Even the mornings, which look a little cleaner, are still hitting that poor surf mark. Thursday the 21st sees that energy jump a bit – the combined energy hits 422 – but the swell’s still just 5 ft of short-period wind chop, and it’s still onshore. Not surfable.
The weekend of the 22nd and 23rd is more of the same. The swell drops back to around 3.5 ft, the period is still down around 7 seconds, and the wind just keeps messing with it. There’s no clean face to be had.
Then we get into the next week, and there’s a flicker of something. On Monday the 24th, that combined energy pushes up to 440, and again we see 5 ft, but still with a 7-second period. It’s just a mess of whitewater, not a wave. The following Thursday the 27th, we see the biggest swell of the period, hitting 5.5 ft, and the energy reading is the highest at 527. But again, it’s all short-period from the ESE/SE, and the wind is on it. That size on Banzai with that period and wind? That’s a closeout.
The water’s about average for this time of year, so no surprises there in terms of the temp.
So, looking at the whole run, there’s nothing here for the paddle surfer. Honestly, with that persistent onshore flow and the steady southeast wind swell, it’s looking more like a kiteboarding setup than a surfing one. The waves are going to be lumpy and blown out. Keep the board in the car.

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.
