The Lowdown
Alright, let's cut to the chase. The 16-day outlook for Banzai is looking bleak, real bleak. We've got a long stretch of nothing on offer, a real dead period. The first week-plus is basically a write-off, with only junky, weak, onshore swells. You're looking at a gap of over a week before anything even remotely interesting pops up, and even that is a stretch. It's one of those blank spells, but that can change, so don’t write it off completely.
Out at Banzai (Big Island), it’s all small and poor for the rest of August and into early September. Swell heights stay under 4ft, with short, weak periods of 5 to 7 seconds. The wind is mostly onshore from the SSE or ESE, which is terrible for this place. Water temp on the 31st is 85°F, which is around 1°F warmer than average, so it’s just a touch warm but nothing wild.
There's a small bump on the 8th of September, with the swell reaching 5ft and energy at 416, but the direction and wind will just make it a mess. The 11th has a similar story: the afternoon shows 5ft of swell with an 8-second period and energy of 344, but again, that onshore wind is going to tear it to pieces. It’s all just churned-up, poor-quality surf. For a spot like this, it’s more of a kiter's paradise than a surfer's.
So, keep your expectations low for the next couple of weeks. There's nothing worth chasing. Give it time; it can't be this flat and crappy forever, but for now, you're not missing much.

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.
