The Lowdown
Alright, it’s Rusty. Look, I gotta level with you: the next sixteen days at Banzai are a rough stretch. This reef can fire, but only if everything lines up, and right now nothing does. It’s all onshore or cross-onshore wind and small, weak swell from the start to the end.
Tuesday the 11th of August starts off with a risk of thunderstorms and a 12 mph ENE breeze blowing cross-on, making it choppy. The swell is only about 3 ft from the ESE with a short 7-second period, and the energy is weak. Water temp is 85°, about normal for August. It’s poor and stays that way through Wednesday and Thursday, as the wind stays onshore and the swell stays tiny, even when the energy picks up a notch on Thursday afternoon.
We get a bit more size on Friday the 14th and Saturday the 15th, with waves around 5 to 6 ft and periods stretching to 8 or 9 seconds. The energy gets strong, especially Saturday afternoon. But it doesn’t matter because the wind is still cross-on or onshore from the ESE or SE at 12 to 15 mph, and the conditions are described as poor and choppy. That much energy with that wind on a reef makes it look better for a kite than a surfboard.
From Sunday the 16th through Wednesday the 26th of August, it’s the same sad song: tiny swell, short periods, and wind that never cleans it up. There’s no window of glassy, offshore wind anywhere in that stretch. If you’re hoping for a wave, this forecast ain’t giving you one. Sometimes you just gotta wait for the next one.
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.
