The Lowdown
Alright folks, Rusty here. Let's have a look at the only spot on the menu for this 16-day stretch: Banzai. Straight off the bat, I gotta be honest with you, this ain't looking pretty. We're staring down a long, dry spell with not a single "good" session on the cards. The whole forecast window is basically a write-off, and that's just how it goes here sometimes – a blank run is pretty normal for this area when the conditions don't line up.
Right now, on Sunday the 16th of August, there’s a bit of swell running, about 6ft from the ESE with a moderate energy (688). But it's totally ruined by a risk of thunderstorms and a cross-onshore wind. The water is sitting at 85°, which is about average for this time of year. The surf is poor and choppy. Monday the 17th isn't any better – the swell drops and the wind stays ugly. We go through Tuesday and Wednesday with tiny, weak swell and poor conditions. Honestly, from now until the end, every single entry says "poor surf conditions" and scores a zero.
There are some moments where the swell pops up a little, like on the 22nd of August, Saturday morning, with 5ft from the ESE and moderate energy (368). But again, it's cross-onshore and choppy. Not a single clean, offshore window in the whole run. The swell directions are all from the SE or ESE, and the optimum for Banzai is from the south, so it’s never really hitting right anyway. The period hovers around 7-8 seconds for most of it – short-period, weak, wind-affected slop.
So what's the verdict? There are no standouts. The best you could even call a "maybe" is a few mornings or afternoons where the wind is light, but the swell is non-existent – like 1ft or 2ft. That’s barely a ripple. Save the drive. Keep an eye on the charts; things could change, but for now, Banzai is a stay-home kind of place. This is a classic case of a long stretch with absolutely nothing to get excited about.
Rusty, signing off.

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.
