The Lowdown
Alright, surfers. Rusty here. I gotta be straight with you—this is a rough one. The 16-day window for Banzai looks like a total write-off.
Let’s start with Banzai, a reef break that’s fairly consistent and exposed to the south – that’s the optimum direction. The water’s sitting at 84°, which is about normal for this time of year, so at least a dip will feel nice.
But that’s where the good news ends. From Wednesday afternoon, August 12th, right through to Thursday morning, August 27th, every single session is flagged as "poor surf conditions." The swell is coming from the southeast, which is fine, but the period is short, hanging around 6 to 9 seconds. That’s weak, windswell stuff. The combined energy of all swells directed here starts at a weak 39 and never gets above moderate. The biggest spike we see is on Friday, August 14th, with a 7ft swell from the ESE, but that’s got a period of just 8 seconds and the wind is a cross-onshore, making it messy and choppy. That swell at 7ft is getting a bit too big for beginners, but with the wind on it, it’s not even clean for experts.
The wind is a constant problem. Most of the time it’s onshore, cross-on, or cross-shore, ranging from a light breeze to a fresh breeze at 19 mph. There are a few windows of glassy or offshore wind, but they don’t line up with any decent swell. The whole period is a classic case of bad timing.
There’s a gap of about 12 days where the score is zero. Honestly, with this setup and the strong onshore winds, this looks more interesting for kite surfing than paddle surfing. The wave energy is just too weak and the conditions too poor to get excited about anything.
The energy peaks on Friday, August 14th, with a reading of 904 (moderate), and again on Sunday, August 16th, with 589 (moderate), but it’s all wasted by the onshore winds and short period. There’s nothing to recommend here.
Hang in there, it won’t be like this forever.
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.
