The Lowdown
Alright folks, Rusty here. Let's have a look at what Banzai has in store for us over the next couple of weeks.
Honestly, I'm looking at the forecast and it's a bit of a bummer. For the first week and a half, Banzai is pretty much a write-off. We've got a long stretch of nothing but onshore winds and grotty conditions. The water's sitting at a warm 85°F, which is about normal for this time of year, so that's one small comfort. But from Friday, the 28th of August, right through the end of the first week it's a constant stream of onshore wind from the SE and ESE. The swell is small, mostly under 3ft, with a frustratingly short period of just 6 seconds – that's just windswash, not proper surf. The combined wave energy is weak, often under 100, and the wind just makes it a choppy mess. It's a tough run, with no real windows for a decent paddle.
We finally get a little glimmer of hope on the 9th of September, a Wednesday. The swell starts to build to 7ft from the ESE, and the period stretches to 8 seconds. The wave energy jumps up to (919), which is a solid pulse, but it's still onshore from the SE. This is a big, messy wave. It's marginal at best, and honestly, for a heavy reef like Banzai, 7ft of onshore, bumpy swell is a dicey proposition. This is expert territory at that size, and with the wind all wrong, it's more of a spectacle than a good surf. It might look more interesting for the kite surfers than for us paddle guys.
The best of a bad bunch looks like it might be the morning of the 12th of September, a Saturday. The swell drops back a touch to 6ft from the ESE, with an 8-second period, and the wind swings to an ENE cross-on at only 6 mph. That light breeze will keep the surface a bit cleaner, and the wave energy is still moderate at (560). It's still not offshore, but it's the cleanest we're going to see. It's a marginal call, and for advanced surfers only, but if you're desperate, that's the morning to circle on the calendar. There's nothing in this window that I'd call a standout. It's a long, dry stretch before that last weekend, and even then, it's just a promise of something better, not a guarantee.

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.
