The Lowdown
Alright folks, Rusty here. Let's be straight with you – the next couple of weeks are looking pretty flat and grim for Banzai. We're in for a long stretch of small, onshore slop with no real juice to get excited about. The water temp is sitting around 85°, which is about average for this time of year, so nothing unusual there.
The outlook kicks off Thursday, September 4th, with a tiny 2ft swell from the SE, a weak 5-second period, and a light onshore breeze. The wave energy is next to nothing at just 21. Don't bother paddling out – it's a waste of wax. This pattern of small, short-period, onshore junk continues day after day. Friday, Saturday, Sunday, Monday, Tuesday – all the same story. Swell hovers between 2ft and 3ft, period stays between 5 and 7 seconds, and the wind is consistently from the SE or ESE, blowing straight onshore. The combined wave energy stays under 100, so it's all weak and messy.
We do get a bit of a pulse rolling in on Wednesday, September 9th, with the swell jumping to 5ft from the ESE. The period only hits 7 seconds, and the energy climbs to 385, which is finally moderate. But don't get your hopes up – the wind is still onshore, and the wave comment is still "poor surf conditions." It's a bit of a tease.
The next week is more of the same. Thursday the 10th sees a slight drop back to 4ft, with a cross-onshore breeze, and the energy falls to 143. The surf is still poor. Friday the 11th is similar, with 4ft swell and 193 energy. The best looking day in the whole 16-day window is Saturday, September 12th. We get a 6ft ESE swell with an 8-second period and a solid 585 combined energy. That's a legitimate bump. But here's the kicker – the wind is howling onshore from the SE at 16 mph, and the wave comment is still "poor surf conditions." That size with that wind is going to be a washing machine. It's too big for beginners at over 5ft, and with the onshore wind, it'll be a bumpy, blown-out mess better suited for a kite than a paddle.
The rest of the run into mid-September is a slow fade. Swell drops back to 4ft to 4ft, and we get some cross-onshore winds from the East on the 13th and 14th, making it choppy. By the 15th, we're back to tiny 3ft swell and weak energy. There's nothing in this 16-day window that offers a proper wave. For a break like Banzai, which is a fairly consistent reef, it's a tough run. It tends not to stay this poor for long, but for now, the best advice is to leave the board in the car and go find something else to do.
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.
