The Lowdown
Alright, Rusty here. Let’s break it down for Banzai. This 16-day stretch is a rough one, and there’s no point pretending otherwise. The water temp is 85°F, pretty much normal for this time of year.
The first week is a total loss. From Saturday the 22nd through the end of the month, it’s poor. The wind is hammering from the east and southeast, onshore or cross-onshore, and the swell is tiny and weak. Wave heights are mostly 3 to 5 feet, with a short period of 6 to 7 seconds, and the combined energy is mostly in the double digits (54 to 93), with a few afternoons scraping into the low 100s. It’s choppy, weak, and not worth suiting up for.
We’ve got a gap of nothing until Sunday the 30th. The afternoon finally gives us a glassy moment. The swell is 4ft from the ESE with an 8-second period, and the combined energy is 188 (moderate). It’s described as “surfable waves but very ordinary.” That’s not a rave, but it’s the first time the wind cooperates. If you’re itching, that’s the window.
The real standout is Monday the 31st in the morning. The swell jumps to 7ft from the SE, with a 9-second period, and the combined energy hits 688 (moderate to strong). The wind is a light cross-shore from the NE – that’s a big upgrade. It’s the biggest, cleanest swell of the whole forecast. The size is into intermediate territory, but it’s still called “marginal” due to tide issues. Even so, this is the best you’ll see.
After that, it’s back to the grind. From Tuesday the 1st of September, the swell drops to 4 to 5 feet, the period goes short again, and the wind turns back onshore. The energy fades to the low 200s and then down to under 100 by the end of the week. Small, choppy, and forgettable.
So, to sum it up: Monday the 31st morning is the one to aim for. The rest is a long, quiet stretch. That’s just how it goes here sometimes, but forecasts can change, so don’t lose hope entirely.
Rusty, out.

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.
