The Lowdown
Hey, Rusty here. Let's break down the next 16 days for Banzai. It's a bit of a slow burn, so don't expect a full-blown swell event.
The first flicker of life shows up on Sunday, July 19th. The morning session has a pulse of 6ft from the ESE, with a 8-second period. The combined energy reads 580, which is moderate, but the wind is a gentle onshore breeze from the ESE, so it's going to be bumpy. It's a 'marginal' call at best. The afternoon drops to 4ft from the SE and the energy falls to 216. Still onshore, still messy.
From Monday, July 20th, through Saturday, July 26th, we're in a pretty flat and choppy pattern. The swell sits around 3ft to 5ft, mostly from the SE or ESE, but the wind is stuck onshore or cross-onshore. The combined energy is weak, bouncing between 96 and 274. The surf will be a jumbled mess of wind chop. Nothing to write home about. There's a brief bump in energy on the morning of Sunday the 26th (274) with 5ft from the ESE, but the cross-onshore wind will ruin any chance of a clean wave.
The one standout, if you can call it that, is still the morning of Sunday, July 19th. That 6ft from the ESE with the 580 energy reading is the biggest push of the whole forecast. Banzai is a reef, so it can handle the size, but it's advanced territory. The water temp is about normal for the time of year.
The second week, from July 27th onward, is the same sad story. Small, weak swell with combined energy values mostly under 200, and a constant onshore breeze. The morning of July 30th offers a 4ft pulse from the ESE, but with only 184 energy and cross-onshore wind, it's still a no-go.
So, to be honest, the best advice I can give is to keep your board in the car, but don't get your hopes up. Sunday the 19th is the only chance for any size, and even then it's rough. It's going to be a quiet stretch.
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.
