The Lowdown
Alright, Rusty here. Let's talk about what's on the menu for the next couple of weeks.
Truth be told, it's a pretty grim stretch for Banzai. We're looking at a solid 16 days of mostly onshore or cross-onshore winds, with the swell direction coming from the South and Southeast, which is pretty much the wrong direction for this spot. The water temp is sitting at a normal 83.3°F for this time of year, so that's not the issue. The issue is the wind and the swell combo. For the first nine days, from Thursday the 16th to Friday the 24th, the forecast is a write-off. The wave energy is weak, with the combined energy reading just a measly 33 (weak energy) on the Thursday morning, and even when it bumps up to a moderate 248 on the Sunday, the wind is still cross-onshore, making for choppy, poor surf. It's a long, dry spell, about nine days of nothing worth paddling out for.
We start to see a glimmer of hope on Sunday the 26th of July. On the Sunday morning, the swell picks up to 5.6ft from the ESE, with a period of 8 seconds. The combined energy hits a strong 537 (moderate wave energy), and the wind is a gentle cross-onshore from the ESE. The forecast calls it a "marginal" call, which is the best we've seen all window. The size is starting to get up there, but it's still not clean. The wind is still cross-onshore, so it's not going to be glassy, but it's the best of a bad bunch. The Monday morning after that, the 27th, we get a light cross-shore wind from the ENE, but the swell drops back down to 3.6ft from the SE, and the energy is weak at 112. Not really a standout.
Honestly, there's no true standout here. The whole run is plagued by poor wind alignment. The Sunday the 26th morning is the only day that even looks like it might be worth a look, but you'd be paddling out into a messy, cross-onshore breeze. For a spot like Banzai, which is an exposed reef and needs a clean S swell with offshore NW winds, this is a total bust. If you're into kite surfing, the wind might be more interesting than the waves.

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.
