The Lowdown
Alright folks, Rusty here. Let's get honest about what's cooking at Banzai. Straight up, this is a tough outlook. The whole 16-day window is a real struggle. We're looking at a long stretch of nothing special, with poor surf conditions dominating almost every single session. You'll be waiting a long time for anything half-decent.
The first real chance of anything rideable doesn't show up until Sunday, August 16th, and even then it's marginal. The best of a bad bunch looks to be that Sunday afternoon. The swell bumps up to 6ft from the ESE with a period of 8 seconds, and the combined energy hits 655 (moderate wave energy). But here's the catch – the wind is a moderate cross-shore from the ENE, which will leave a chop on the surface. It's a step up from the constant onshore junk we've had, but it's still a far cry from clean. For a reef break like Banzai, that cross-shore breeze is a buzzkill, making it feel more like a battle than a joyride. The water temp is a warm 85°, which is about normal for the time of year.
For the rest of the run? It's a write-off. The wind is almost always onshore or cross-onshore, from the SE or ESE. That's the kiss of death for this spot. The swell period is stuck at a short, weak 6-8 seconds, so no real power or shape to speak of. The energy readings are mostly in the double or low triple digits, just confirming how weak it all is. Even when the swell height gets up to 5ft or 5ft, the wind and poor quality make it a chore. This is a classic case of the setup being more interesting for a kite than a paddle.
Stay patient, wait for a change in the forecast, and don't get your hopes up for this run. It's a long, flat spell for Banzai.
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.
