The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this is a rough run for Banzai. The whole 16-day window is a write-off for decent surf. We’re looking at a solid stretch of nothing but onshore junk and tiny, weak waves. The first recommendation doesn't even show up until we start looking, and it’s all downhill from there.
Starting Saturday, July 18th, the wind is hammering straight onshore from the ESE at 9 mph, with a weak 5 ft swell from the same direction. The period is a short, gutless 7 seconds. The combined energy is a lousy 389, which is moderate, but with that wind, it’s just a messy, blown-out shambles. The water’s sitting at 84°F, pretty normal for this time of year.
That pattern just stays locked in for days. Every morning, every afternoon, it’s the same story: SE or ESE winds blowing straight into the break, with tiny swell heights of 3 ft to 4 ft and periods of 6 to 8 seconds. The energy levels are pathetic, mostly in the double digits or low triple digits. For example, on the morning of July 23rd, the energy is just 62, and on the afternoon of July 28th, it’s 75. That’s weak.
The wind doesn’t let up. It’s onshore or cross-onshore the whole time, keeping the surface choppy and ugly. There’s no shoulder to work with, just closeouts or fat, weak lumps. The only slight change comes on the morning of July 30th, where the swell bumps to 6 ft ESE with an 8 second period and energy hits 529 – still moderate, and still onshore. It’s not even close to being good. It’s just a bigger mess.
The whole period is a dud. There’s no standout. No hidden gem. This is just one of those stretches where you leave the board in the car and go do something else. Forecasts can change, but for now, it’s a dead run.
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.
