The Lowdown
Alright folks, Rusty here. Let’s get straight into it.
Look, I’ve got to be honest with you – the next couple of weeks are looking pretty grim for a proper paddle. We’re staring at a long stretch of onshore, mostly SE wind and weak, short-period swell that’s just not going to give us anything worth waxing up for. The first real surf on offer doesn’t show up until Tuesday, September 1st, but even then, it’s a write-off. The water’s sitting at 85°F which is about average for this time of year, so at least you won’t be cold while you’re watching the wind chop.
From Tuesday, September 1st, right through to the end of the 16-day window, Banzai is getting hammered by onshore wind. The swell is tiny – mostly between 2ft and 4ft – and it’s coming from the SE with a short, weak period of 5 to 8 seconds. That’s just windswell, and it’s all going to be blown out and bumpy. The combined wave energy is weak, sitting mostly in the double digits and low hundreds (e.g. 111 on Tuesday morning, 262 Tuesday afternoon), but it’s all poor surf conditions. There’s no standout period here, not even close. If you’re a kiter, maybe this setup looks interesting, but for a surfer, it’s a solid pass.
The best on offer? Honestly, there isn’t one. The closest thing to a spike happens around Thursday, September 10th, when the swell bumps up to 6ft out of the ESE with an 8-second period, and the energy jumps to 685 – that’s moderate. But the wind is still onshore from the SE at 16 mph, so it’s going to be a mess. Banzai is a reef break, and it’s fairly consistent, but with the wind and swell direction coming from the SE (the opposite of the optimum S direction), it’s not going to line up. This is one for the experts only, and even then, it’s a frustrating session.
After that, the surf fades again. By the second week, we’re back to tiny, weak dribble – 2ft to 3ft, period 6 to 7 seconds, all onshore. There’s a brief moment on Monday, September 14th, with a clean-ish light breeze from the ESE at 6 mph, but the swell is only 3ft and the energy is weak (79). It’s not enough to get excited about.
So, sorry to be the bearer of bad news, but there’s nothing worth chasing in this 16-day window. It’s a flat, blown-out run. The forecast can always change, but as it stands, leave the board in the car and go do something else.
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.
